Updated Sunday July 28, 2013 by Greg Grant Basketball Leagues.

Greg Grant Basketball & Training Center


For the purpose of its league games, the Greg Grant Basketball & Training Center will use Michigan High School Basketball Michigan Rules. However, in all cases during play, specific Greg Grant Basketball & Training Center league rules will override the High School Rules.


Any team using an ineligible player in any authorized league game, upon protest of the individual’s eligibility by an opposing team or Greg Grant Basketball & Training Center staff member shall forfeit the game(s) in which the individual has participated. Specific eligibility rules are listed below:

A. All players must be eighteen (18) to be eligible to participate in Adult Leagues, unless approved by the Greg Grant Basketball & Training Center Athletic Staff.

B. Roster Requirements: 8 player minimum.

C. No player is allowed to participate on more than one team in his/her respective division, but may play in different divisions or leagues simultaneously.

D. No player may participate until his/her Player Registration and Waiver completed online or by form in person, and appropriate individual player fee is submitted to the Greg Grant Basketball & Training Center.

E. Due to eligibility regulations, members of high school/college basketball teams cannot participate in the Greg Grant Basketball & Training Center program anytime during their high school or college basketball season.

F. No player may play under an assumed name.

G. Players may not be added after the Player Add date, which is before the start of the fifth game.

H. Players must participate in at least three (3) regular season games to be eligible for playoffs.



A protest will be accepted on the basis of eligibility. Any team captain/coach may lodge a protest of eligibility under the provisions listed below:

A. Any protest of eligibility must be made before, during, or within 5 minutes after the conclusion of the game.

B. In the case of an eligibility protest, rosters will be on site.

C. Player(s) in question must present a picture I.D. to verify their eligibility.

D. Greg Grant Basketball & Training Center staff will make the final decisions regarding protests.

F. Any player who is judged to have played illegally shall be suspended for a minimum of four games from any team that he/she is a valid member of. The coach of the team for which a player plays illegally will also be suspended for a minimum of four games. As all other suspensions, suspensions of this nature will carry over into the next season if not completed during the current season.

G. All Greg Grant Basketball & Training Center rulings are final. Protests of eligibility not covered in this rule shall be handled by the Greg Grant Basketball & Training Center League Athletic Director in the spirit of these rules.



Teams may enter the gymnasium area fifteen (15) minutes before their scheduled game for that night. Please do not enter court area until previous games have been completed.



Prior to the start time of the game, teams will have a five (5) minute warm-up period on their assigned court beginning at their scheduled game time. Note: If a game is running behind schedule, the referee may waive the five minute warm-up period. Use of courts reserved for pickup games is prohibited.



A. Teams are recommended to be at their court five (5) minutes prior to their scheduled game time.

B. A five (5) minute grace period will be instituted if one or both teams are not ready to begin play at the assigned time. If at the conclusion of this five minute grace period one of the teams are not ready to begin play, a forfeit will be declared. The five minute grace period start’s at the time the court has been assigned for your game, not at the end of the warm-up period.

C. To start a game, teams must have at least one fewer players than the particular league that they are participating in, (e.g. 5-on-5 games must have at least 4 players per team to start play, 4-on-4 must have 3 players, etc.). However, if a team has no substitutes to replace disqualified players, it may continue with fewer than 4. When there is only one (1) player participating for a team, the team forfeits the game unless the referee believes that the team has an opportunity to win the game.

D. If a forfeit is determined due to lack of players, and if both teams desire, the teams scheduled to play at this time still have the rights to the court and may play a scrimmage or pick-up game which will not count in the standings. Note: scrimmage games will not be officiated.



For all leagues, courts will be assigned for game’s in one (1) hour time slots. Upon completion of your game you may stay on the court until ten (10) minutes before the start of the next scheduled game.



In addition to the roster the Greg Grant Basketball & Training Center has on file, all captains/coaches must verbally submit the games active line-up to the scorekeeper five (5) minutes before game time. All team members may need to check-in with the scorekeeper during the warm-up period and present their Drivers License for roster verification.



Only the captain/coach may address the official. Players may only address the official through their captain/coach.



There will be no protests on officials judgment decisions. Protests involving rule interpretations of the game, must be brought to the attention of the head official & scorekeeper at the time of the dispute.



A coach’s or player’s second ejection of the season will result in an automatic two game suspension, the third ejection will result in a three game suspension, etc. This suspension will also carry over into the next season if there are not enough games in the current season to complete the full suspension. Zero Tolerance - No Fighting - player will receive an automatic league suspension without refund. Any player ejected from the game for fighting shall be suspended a minimum of two (2) games. The Officials shall report all such incidents to the League Director.  All appeals or protests of suspensions must be given to the League Director in writing. Final decisions regarding suspension and ejections are up to the League Director. If a player receives a season or indefinite suspension, Greg Grant Basketball & Training Center reserves the right, to suspend that player for any/all leagues that player is participating in for that season. No refunds will be issued to teams/players suspended.



The purpose of this rule is to provide guidelines for officials and coaches as to their responsibilities during a contest should an injury or illness occur which results in a player losing blood or other body fluids.

A. As soon as the game official can see or has their attention called to a player who is bleeding, they are to stop the contest as soon as possible.

B. The player must leave the game at that point. The custodian on duty or the building supervisor will be responsible for cleaning up the floor if necessary.

C. The injured player must have the wound cleaned up, bleeding stopped and wound covered before being allowed to re-enter the game.

D. The injured player must re-enter the game as a substitute by rule.



Greg Grant Basketball & Training Center reserves the right to remove any spectator(s) from the facility during basketball games for the purpose of public safety. Spectator(s) will be removed due to disparaging language and/or unsportsmanlike conduct which interferes with the normal and efficient running of the game. Please be advised that captains can be held responsible for their

spectators conduct.



A team moving-up to a higher division will be determined at the discretion of the Athletic Office. The decision will be based on the team’s previous season(s) performance and current team roster.



A. No “equipment” or jewelry may be worn by players. The only exceptions to this rule are: flat wedding bands may be worn if covered with tape and (or) religious or medical necklaces which must be securely taped underneath the team uniform.

Greg Grant Basketball & Training Center reserves the right to classify the level of play for any team registered in our league.



A. Any team that forfeits two games in a given season, with the exception of forfeits resulting from the use of ineligible players or having an insufficient number of players to play because of an ejection, will forfeit all their remaining games unless the offending team pays a league re-entry fee of $50.00.

For technical fouls, refer to the MHSAA basketball rule book. Referees have been instructed to handle technical fouls in the same manner they would during High School games. As a reminder:

must leave the building.

D. After a player's third technical foul in a season, he/she will be suspended for one game. Every second technical foul after that will merit an additional game suspension.  This applies to the regular season as well as the playoffs.

E. Fighting between two players will result in a flagrant technical foul and immediate ejection of both players from the game. Each team will shoot two (2) free throws and the alternating possession arrow will determine who gets the ball. Note: a single

player can also be called for a flagrant technical as a result of fighting or hitting an opposing player.

F. A break-away foul which is intended to do bodily harm to the offensive player, will result in a flagrant technical foul and ejection.



Only eligible players, captain’s and a scorekeeper will be allowed on the team’s bench or surrounding area. All spectators and children must sit in the designated spectator area, with adequate supervision. Failure to comply will result in a technical foul being assessed and the removal of unauthorized bench personnel to the spectator area.



A. Technical fouls will be assessed for any vulgar, disparaging or threatening language and (or) gestures, or any other unsportsmanlike conduct from a benched player, player/coach or manager.

B. Coaches, a scorekeeper and other bench personnel must remain seated on the bench at all times. The exceptions to this rule are players rising in front of their bench to spontaneously react to and outstanding play by a teammate or to acknowledge a replaced player. A technical foul will be assessed for infractions of this rule.

Taunting includes any actions or comments by coaches, players, or spectators which are intended to bait, anger, embarrass, ridicule or demean others, whether or not the deeds or words are vulgar or racist.  Included is conduct that berates, needles, intimates or threatens based on race, gender, ethnic origin or background, and conduct that attacks religious beliefs, size, economic status, speech, family special needs or personal manners.

Examples of taunting that would lead to ejection include but are not limited to, “trash talk;” physical intimidation outside the spirit of the game; reference to sexual orientation; "in-the-face" confrontation by one player to another; standing over/straddling a tackled or fallen player.

In all sports, officials are to consider taunting a flagrant unsportsmanlike foul that disqualifies the offending bench personnel or contestant from that contest/day of competition (and the next contest/day of competition). A warning may be given but is not required before ejection.

At all MHSAA tournament venues, tournament management may give spectators one warning for taunting. Thereafter, spectators who taunt others are to be ejected by staff.
