CYBA Recreational League Rules

Please take time to read all of these rules. They will help you with practice and game situations/strategy.

3rd -12th Grade Rules Regulations

  • Practices can only be held in authorized CYBA facilities which may include gyms at Columbia Public School, Our Lady of Lourdes Interparish School (Columbia Catholic School), Father Tolton Catholic High School, Christian Fellowship, etc.  If other locations are added, you will be notified.
  • Each team will be permitted one practice of 90 minutes per week. If a scheduled practice is cancelled due to weather or other school activity, the missed practice may be made up if a time can be worked out with the facility at which you practice or at another CYBA authorized facility.   
  • Teams may share gym space with other CYBA teams.  Teams may use their time to practice together, separately or scrimmage other CYBA teams.
  • Teams may scrimmage other CYBA teams within their allocated practice times.  If a CYBA team visits another authorized CYBA practice location other than their usual site, that scrimmage will count as their practice time for that week.
  • CYBA teams can not scrimmage any non-league teams at CYBA authorized or non-authorized facilities.
  • If a team is not  going to practice during their regular practice time, please notify your building administrator that you will have a vacancy (they can use your time for someone else that week) please give as much notice as possible.
  • Any violation of practice will be taken seriously and will reflect upon the individual coach.  Knowingly having more than one practice will result in the dismissal of the coach.

Player Participation & Substitution Rules

For grades 3-8

Number of Players/Playing Time:

10--All players will play 20 minutes.

9--Five players will play 20 minutes.
Four players will play 25 minutes (if you consistently have 9 players, it is required that the 25 minutes playing time will be distributed evenly over the course of the season alternating from game to game).

8--Each player will play 25 minutes.

7--Five players will play 30 minutes; two players will play 25 minutes.
The playing time will be distributed evenly over the  course of the season, alternating from game to game.

6--There will be some flexibility with normal substitution rules as worked out before the game with the references and opposing coach.

It is highly recommended to work out your substitution pattern in advance of game time to eliminate having to make judgments during the game that may not be accurate.  Coaches are required to have a written, verifiable player rotation.  Referees/scorekeepers have the right to ask for that rotation.

  • Substitution rules apply to leagues for Grades 3rd-8th only.
  • It is mandatory to substitute every five minutes regardless of the number of players on your team.  When the substitution time-out occurs, you must clear your bench unless you have eleven players.
  • No substitution will be made at any other time unless an injury occurs or a player fouls out.  You cannot substitute during time-outs unless a player is injured or fouls out.  If that occurs, you must notify the referee that you are doing so.  Failure to substitute according to the rules can result in a technical foul.
  • If a player leaves during the course of a game and the coach is aware prior to the start of the game, the coach must notify both the officials and the other coach prior to the start of the game itself.  If a player leaves because of illness, emergency or any other reason during the game, the coach must notify the officials and make every effort to play the remaining players equally.
  • Failure to comply with these rules can result in the forfeiture of the game.
Technical Foul Rules
  • Note that technical fouls are cumulative for the entire season.
  • Player Technicals:
    • 1st Technical: normal rules apply.
    • 2nd Technical: ejection from game and suspended for next game.
    • 3rd Technical: ejection from game and suspended for the rest of the season

For example, if a player receives a technical foul in game one and then another in game three, the player will be ejected from the game and suspended for the following game.  Should the player receive a third technical, then the player will be suspended for the rest of the season.

  • Coach Technicals**:
    • 1st Technical: normal rules apply
    • 2nd Technical: ejection from the game and suspended for the rest of the season.

**Rulebook technical fouls do not count against the coach nor do any technicals assessed to the team due to spectators behavior.**

  • If a technical is called on a spectator, they will be asked to leave the gymnasium (and cannot watch) for the remainder of the game.  A second technical during the season will result in suspension from all playing facilities for the rest of the season.
  • Verbal or physical abuse of referees, coaches, players or other spectators will not be tolerated. Violators may be asked to leave or, if necessary, removed from the facility.
  • If you are suspended from the season for technicals, you will not be refunded your registration fees.

Loud/constant yelling from coaches from the sidelines during games will not be tolerated.  Giving direction to your players is important, however, it must be done within the confines of the Coaches Box.  Also, our facility staff/referees can use their discretion if behavior is 'over the top' or excessive. 

There can only be two (2) coaches on the bench with only one (1) coach standing within the Coaches Box, everyone else must be seated on your team's bench.  The officials will issue an initial bench warning, if more than two (2) coaches are on the bench.  After issuing the warning the officials can issue a technical foul, if there continues to be more than two (2) coaches on the bench.    

CYBA hopes everyone has a great season and enjoys their experience volunteering to help kids play the great game of basketball.  If any coach has a question or issue they need help with, please contact us and we will be glad to help you.
