The Colorado Lacrosse Games
Youth: We will follow US Lacrosse Rules, unless modified herein.
High School Divisions (Rising & Elite): We will follow NFHS Rules, unless modified herein.
a. 10 players from each team on playing field (3 Attack, 3 Midfield, 3 Defense, 1 goalie).
b. Maximum of 4 long polls on the field for each team.
c. Recommended team size 17-25 players (minimum 10).
d. Quick restarts will be implemented.
e. On flag down, the fouling team must gain possession before play is blown dead. The play can be called dead when the ball exits the playing field. Loose ball does not blow the play dead.
All fields will be regulation size whenever possible. If a field is not regulation size, both teams will be notified by game officials before play begins.
Games will be scheduled in 60 minute blocks to allow for any delays that arise.
- Two (2) twenty five (25) minute running time halves.
- Two (2) Timeouts per a game, per a team. Timeouts may be used at any time during the game.
- Timeouts will be one (1) minute in length.
- The timeout will stop the clock.
- Ties will be determined by a 5 minute sudden death overtime, followed by braveheart.
- Halftime will be five (3) minutes.
- The last two (2) minutes of the game will be stop time unless there is a 3 or more goal lead.
- Timeouts are allowed to be used in the final 2 minutes.
- Penalties ARE stop time.
Clarification on game clock and penalty time:
The game clock will never stop except for the last 2 minutes of the game (unless there is a 3 goal or more lead). Official's time out or team timeout will stop the clock. All penalties will be stop time! Table staff will keep game time and penalty time. The only timing that game officials will keep will be for timeouts. The scorer’s table game clock will be considered the official game clock.
The official score will be kept by both the table staff and one of the game officials. The table staff and the scoring official will confer after each goal and at all timeouts and period ending points to ensure score accuracy. After game is concluded the table staff and the scoring official will verbally agree on the final score before it is reported to tournament administration. The scoring official does not need to sign the score sheet.
Penalty time will carry over from one half to the next.
In general, Boom Town tournaments will consist of a pool play/qualifying phase. Certain divisions will play only round robin games in order to meet the minimum game guarantee and prevent playing teams multiple times. Seeding and placement for the playoff phase will be determined by results in the pool/play qualifying phase. Only the top 2 teams from each division will be invited to play in the championship game. Rules for breaking seeding ties will vary slightly at each tournament based on the number of teams in each division. Seeding/tie break rules for each individual tournament will appear on the published schedule/bracket documents as they are released.
**In the event a division has an uneven amount of teams, some teams may play an extra game, so only the first 5 games will be applied to the criteria.**
Roster Size: A team must have a minimum of 10 players (1 goalie and 9 field players) present to begin a game. If, after the 15 minute grace period (outlined below in “forfeit” section), a team does not have the required minimum players the opposing team will be awarded a forfeit win. Roster maximum is 25.
Rosters are considered locked after the first game for each team begins.
Each player is allowed to be listed on only one roster and play only for that team during the entire tournament. Even if teams in different divisions are from the same club program, players are not permitted to be listed on more than roster or play for more than one team.
For the High School divisions, all players on the roster must still be in high school. No players can have graduated before the event date (**see note about post-graduate players below). In the event a team does not fall in an offered age division, the team will either be placed in the next closest age division above or below it normal age criteria.
For youth & HS divisions (U11, U13, U15, & U17) the age cutoffs are as follows:
U9: all players must have been born on or after June 1, 2008 or 2027 Grad
U10: all players must have been born on or after June 1, 2007 or 2026 Grad
U11: all players must have been born on or after June 1, 2006 or 2025 Grad
U12: all players must have been born on or after June 1, 2005 or 2024 Grad
U13: all players must have been born on or after June 1, 2004 or 2023 Grad
U15: all players must have been born on or after June 1, 2002 or 2022 Grad (No Freshmen/rising sophomores)
Rising Stars: rising freshman, sophomores, and juniors
Elite: rising sophomores, juniors, and seniors. NO GRADUATED SENIORS.
For high school divisions only: Upon gaining possession of the ball inside the defensive half of the field, a team must advance the ball beyond the centerline within 20 seconds. Failure to do so will result in a turnover, and the ball will be awarded to the opposing team at the spot of the violation or 20 yards laterally from the goal.
U15: The defensive 20-second count will be used. The offensive 10-second count will be used.
U13 and under: The defensive 20-second count WILL NOT be used. The offensive 10-second count WILL NOT be used.
The 4 second crease count for the goalie is applicable to all divisions. There are no counts for advancement of the ball in the youth divisions.
Over and Back Rule:
U10-U15: Once the ball has been successfully advanced into the goal area, a team is provided the opportunity to run its offense in its offensive half of the field. If the offensive team carries, passes or propels the ball to its defensive half of the field and the offensive team was last in possession, and last touched the ball (except on shot), the result will be an immediate a turnover or play-on. If the ball does not touch or go over the centerline, no infraction has occurred. Players may legally bat the ball to keep it in the offensive half of the field, but if it is possessed and their feet are in the defensive half, it shall be a turnover.
5th/U11 and older are permitted to use poles
During the final two minutes or regulation play when there is a lead of 2 goals or less, offensive-stalling rules shall be in effect. The team that is ahead is required to “keep it in” once the ball has been brought into its respective attack area.
If necessary, overtime will be a 5 minute “sudden victory” format. The first team to score in the overtime period shall be declared the winner. If no goal is scored in the overtime period, a braveheart will determine the victory. There will be no timeouts allowed in the overtime or braveheart period.
If overtime is necessary to decide a playoff game, the format will be successive 5 minute “sudden victory” periods with a 1 minute break in between each until a winner is determined. No timeouts allowed in overtime games in the playoffs.
Teams will be allowed a 15 minute grace period to arrive for a scheduled game.
If a team forfeits 2 (two) games in pool play and cannot present a valid reason to tournament administration for doing so, the team will be removed from the tournament.
If a team forfeits 1 (one) game in playoff/tournament play and cannot present a valid reason to tournament administration for doing so, the team will be removed from the tournament.
Note: All forfeit situations will be considered on a case by case basis by tournament administration.
Fighting will not be tolerated at the event. Any player, coach or spectator that is involved in a fight will be immediately ejected from the game and the remainder of the tournament. If the ejected person refuses to leave the field of play or continues to cause a disturbance that prohibits the game from proceeding, staff reserves the right to eject that person from the facility or contact local law enforcement.
In the case of a fight during a game, staff will defer to the game officials to determine which players were involved and should receive punishment. Staff will not take suggestions from anyone other than a tournament official (game official, scorer’s table staff, or tournament staff) as to what players were involved in a fight.
The game officials reserve the right to end a game if the game cannot be safely controlled.
If a player or coach or any other team representative (players & coaching staff) is ejected from a game for any reason other than fighting (player receives 5 penalties in one game, coaches or bench are given game misconduct) that person will be removed for the rest of the current game.
Also they will serve an additional suspension of the team’s next scheduled game including overtime that is attached to the said scheduled game.
Referee calls of any kind are not grounds for protest. Tournament administration will stand behind calls made by game officials and will not change or override any call made on the field of play.
Note on roster checks: If a team suspects that another team is playing with an illegal roster of any kind, the head coach must alert game table staff. Table staff will contact tournament administration. See the definition of an illegal roster below.
Each team in the tournament is allowed to call for only one (1) roster check during an entire tournament and it must come from the head coach. If a roster check is called for Boom Town staff will check the rosters of BOTH teams involved in the game in question. The game clock will stop and remain stopped during a roster check and will not start again until staff gives the go-ahead to start the game again.
All roster checks must be called for during the game in question. Once the game is over, no roster check will be performed.
The following scenarios are deemed by Boom Town as teams using “illegal rosters”:
*Players not listed on the team’s official tournament roster
*Players participating on more than one team in the tournament
*New players appearing for games that are not listed on the official roster
*Players participating that are too old for the division
If during the course of a roster check, it is determined that a team is using an illegal roster, tournament administration will take appropriate disciplinary action. Disciplinary actions may rise to the level of team disqualification from the tournament if the facts of the case warrant such a penalty. The tournament administration reserves the right to administer punishment as it sees fit.
Note: It is allowable for a player to appear for a team after the tournament has begun as long as that player was listed on the original roster before the team’s first game began.
If a jersey switch of any kind becomes necessary during the tournament for any reason (inclement weather, jersey damage, etc) the team must get the approval of tournament administration
Box lacrosse helmets are allowed to be used at Boom Town events.
Goalies will serve their own penalties. If a goalie is ejected from a game, the game clock will be stopped if needed to allow a replacement goalie time to suit up in the proper equipment.
Each team is allowed to call for one (1) stick check per game. The call must be made to the game official and it must occur during a dead ball situation. The clock will stop during a stick check situation.
Coaches are only allowed one stick check per game!
1 minute unreleasable for illegal pocket (stop clock)
3 minute for illegal stick (stop clock)
If a stick is legal the challenging team will either lose a timeout or be charged a technical foul if the team does not have a timeout.
Longpoles are allowed in all divisions
For Elite & Rising Stars Divisions: NFHS rules will be in effect.
For youth divisions (U7, U8, U9, U10, U11, U12, U13, U15): US Lacrosse checking rules will be in effect.
An avoidable body check of an opponent after he has passed or shot the ball is an illegal body check. All stick checks, body checks, legal holds, and legal pushes must be on a player in possession of the ball or within 3 yards of a loose ball or ball in flight
The definitions below supplement, but do not supplant, all aspects, points of emphasis, and Play Rulings of NFHS Rule 5-3.
NO TAKE-OUT CHECKS ARE PERMITTED BY ANY PLAYER AT ANY AGE LEVEL.
A take-out check is defined as:
a. Any body check in which the player lowers his head or shoulder with the force and intent to put the other player on the ground.
b. Any body checks considered more aggressive or more physical than necessary to stop the advancement of the player carrying the ball or to keep or move a player away from a loose ball. This includes but is not limited to: (i) any check in which a player makes contact with sufficient force and intent to knock down the opposing player; (ii) any check in which a player makes contact with sufficient force and intent to injure the opposing player; and (iii) any check made in a reckless or intimidating manner.
c. Any body check on a player in a defenseless position. This includes but is not limited to: (i) body checking a player from his “blind side”; (ii) body checking a player who has his head down in an attempt to play a loose ball; and (iii) body checking a player whose head is turned away to receive a pass, even if that player turns toward the contact immediately before the body check. NOTE: Sports medicine research indicates that the severity of certain injuries may be reduced if a player can anticipate and prepare himself for an oncoming hit. Other sports medicine research indicates that peripheral vision may not be fully developed in many boys before approximately age fifteen. Game officials should be especially alert to blind side checks at all youth levels. U15 and U13 Body Checking is permitted. To be legal a body check should be delivered in a generally upright position with both hands on the stick and the player initiating the check may not use his lowered head or shoulder to make the initial contact. U11 and U9 No body checking of any kind is permitted. Legal pushes In all loose ball situations players should “play the ball,” but incidental contact, “boxing out”, or screening techniques during such play shall not be considered a violation of this rule. If a loose ball is not moving, stuck, or the players are having difficulty picking the ball up the referee may re-start play following the alternate possession rule. Checks Involving the Neck/Head. A player shall not initiate contact to an opponent’s head or neck with a slash, cross-check, or with any part of his body (head, elbow, shoulder, etc.), including any follow through to the head or neck. Blocking of an opponent with the head or initiating contact with the head, including by an offensive player in possession of the ball (known as spearing).
Slashing shall be called per NHFS rules.
U15: Slashing shall be called per NHFS rules.
U13, U12, U11, U10, U9, U8, and U7: Any one-handed check will be considered a slash, whether or not it makes contact with the opposing player.
Any one-handed check will be considered a slash, whether or not it makes contact with the opposing player.
Unsportsmanlike conduct by coaches and/or players will not be tolerated. Obscenities need not be used for language to draw a penalty. Tone, intent, and body language can all contribute to unsportsmanlike conduct. Players and coaches will exhibit the highest level of sportsmanship at all times. This means that in addition to the unsportsmanlike examples contained in NFHS Rule 5-10, any player or coach who uses derogatory or profane language on the field or bench, whether addressing a player, coach, or official may receive: first offense, 1 to 3-minute non-releasable unsportsmanlike conduct penalty; second offense, a 3-minute non-releasable expulsion foul.
U11, U13, U15, & HS
Any player who accumulates 4 personal fouls or 5 minutes in personal foul penalty time shall be disqualified from the game. A substitute for that player may enter the game when the disqualified player would have been permitted to re-enter had he not fouled out.
Note on Weather
Tournament staff will make any and all decisions concerning delaying or cancelling of games due to inclement weather. Officials, coaches, parent or any other non-tournament staff member should not attempt to stop a game because of inclement weather. Any concerns over weather should be addressed to tournament staff.
Tournament administration reserves the right to final say on all matters
