Intramural basketball games will be conducted under the rules of the NFHS – National Federation of State High School Associations with the following modifications:

General Information

  1. All Intramural Basketball games are played at the ARC Gym 1 unless otherwise listed in IMLeagues.
  2. All participants must have their University of Illinois Student Identification Card (i-card) with them at all times – NO EXCEPTIONS.
  3. Team rosters are limited to a maximum of 20 players.
  4. Each team shall designate to the Referee the team captain or captains for the contest. The captain is required to sign the scorecard at the end of each game. The team captain is responsible for all information contained in the Intramural Basketball Rules and Intramural Handbook.
  5. Teams should be warmed up and ready to play as soon as the previous game ends on their court.

Equipment and Uniforms

All players are required to bring a valid UIUC (i-card) to all Intramural basketball games.

  1. The intramural jersey policy is in effect for intramural basketball. The policy reads:
    • Jersey Policy: Participants are required to wear their own team shirts during all Intramural contests. For Flag Football, Soccer, Broomball, and Basketball games teams must have a set of home jerseys and a set of away jerseys.
    • Home jerseys: must be white.
    • Away jerseys: must be any color other than white and each member of your team must be wearing the SAME SHADE OF A SPECIFIC COLOR.
      • This is necessary to ensure that our staff can easily identify team members based on jersey color.  Please refer to IMLeagues to see if you are listed as the home team or the away team.
      • Failure to abide by the jersey policy may result in a forfeit, or technical foul/unsportsmanlike conduct penalty being assessed against your team at the beginning of the contest.  Intramural Managers on duty will have the final say whether a team has acceptable jerseys to begin a contest.  Jerseys will not be available for checkout at Intramural games.
    • All jerseys must be numbered using the digits 0-5 to comply with the National Federation High School basketball rulebook. This means that teams may use any of the following numbers: 0, 1, 2, 3, 4, 5, 10, 11, 12, 13, 14, 15, 20, 21, 22, 23, 24, 25, 30, 31, 32, 33, 34, 35, 40, 41, 42, 43, 44, 45, 50, 51, 52, 53, 54, 55, and 00. Teams may not assign both a “0” and a “00” to different players.  Players who do not have a legal number will not be allowed to play.  Players who enter the game with an illegal number will be assessed a technical foul and must leave the game until they get a legal number.
    • Numbers must be readable, for example no black marker on navy blue shirts.
    • Numbers may not be taped onto jerseys, and may not be written or indicated on players’ arms, legs, or other body parts. Intramural staff is not responsible for supplying markers for teams who do not have numbers on their jerseys.
    • If teams do not have the proper uniforms, they will be charged with a FORFEIT, with all consequences of forfeits applying. If this happens a second time, a team will be charged a second forfeit and will be removed from the league.
    • Players with numbers that are difficult to read as deemed by game officials may also be assessed a technical foul at the start of the game.
  2. Game balls will be provided. Men shall use a regulation size ball while women’s and co-rec teams may use either the regulation or smaller size 28.5 ball.
  3. Only tennis, court, or basketball shoes with pliable synthetic or rubber soles shall be worn. No marking black soled shoes, boots, or running shoes will be allowed.
  4. Baseball style hats, bandannas, and sunglasses are not permitted. No other headwear with knots or dangerous materials is allowed.
  5. Players may not wear casts/splints under any circumstances at any time and all pads/braces must be above the waist. Players who wear a knee brace with exposed metal or metal hinges are required to cover it.
  6. Players may wear kneepads, gloves, covered knee braces, headbands, and knit caps.
  7. Players may not wear jewelry of any type.
  8. Medical Alert bracelets may be worn, but must be taped down while maintaining visibility of pertinent information. Intramural staff will NOT supply materials such as tape or band-aids to tape down medical alert bracelets.

Any equipment, which is unnatural and designed to increase a player’s height or reach or to gain an advantage, shall not be used.

If there is flagrant misconduct, the officials shall penalize by removing any offending player from the game and the area.  In addition, the officials shall banish any offending coach, substitute, team attendant, or follower from the vicinity of the court if ejected.  A player who commits their fifth foul shall also be removed/disqualified from the game (but not necessarily the playing area).
  10. The officials shall have power to make decisions for infractions or rules committed either within or outside the boundary lines from before the scheduled starting time of the game through the referee’s approval of the final score.

    • incorrectly counting or canceling a score.

  14. The scorers/timers will be provided by the intramural department and shall keep a running summary of the points scored. They shall record the personal and technical fouls called on each player and shall notify the referee immediately when the fifth foul is called on any player (personal or technical) and/or a team reaches its seventh or tenth foul in one half.  They shall record the time-outs charged to each team.  They shall keep track of the jump balls for the alternating possession procedure and be responsible for the possession arrow.
