Rules: Section 7 Rules of Play


CMBA games will be played under the current FIBA Official Basketball Rules.  The complete set of these rules can be found on the FIBA website www.fiba.com.

In keeping with the Long-Term Athlete Development model for Basketball, modifications have been made to the FIBA rules specific to each age group and their developmental stages.

CMBA 40 Point Game Spread Mercy Rule

For all age groups and divisions, if one team reaches a lead of forty (40) points at any time, the game will be stopped immediately by the referees and the team in the lead will be credited with the win.  At this time both coaches of each team will be advised by the referees that the game result is official at the current score and will be recorded on the score sheet as such.  Should both coaches agree, play is to continue for the total remaining time left on the score clock. The scoreboard will be set to 0 - 0. The referees will continue to officiate the game and all rules. Referees are obligated to continue to officiate the remainder game with all CMBA rules in effect.
