2023–24 NCAA Division I men's basketball season

On May 5, 2023, the NCAA Basketball Rules Committee proposed a suite of rule changes for the 2023–24 season. These changes were approved by the Playing Rules Oversight Panel during its June 8 conference call.[1][2]

• A defender near the basket must be in position to draw a charge before the offensive player plants his foot to jump during a field goal attempt. If the defender arrives after the shooter has planted his foot, the officials are to call a blocking foul if contact occurs.
• Prerecorded or live video can be transmitted to the bench area during the game, on an optional basis. This had been an experimental rule since 2021–22, but is now permanent.
• Officials will be able to review basket interference or goaltending calls during the next media timeout to ensure the call's accuracy, as long as they were made during play. Review is immediate if a foul is called on a shot that ended with basket interference or goaltending.
• Non-student bench personnel will be allowed to serve as peacekeepers in any altercation.
• If a coach requests a review of an out-of-bounds play in the last two minutes, that team will be charged a timeout if the challenge is unsuccessful.
• The shot clock will reset to 20 seconds for all offensive rebounds when the original shot has touched the rim.
• If a player is called for a foul, and replay officials see that the foul is the direct result of a flagrant foul against the player who was originally charged with the foul, officials can rescind the foul on the victim of the flagrant foul.
• A timeout can be granted when a player has possession of the ball while airborne.
• A player will be disqualified if he commits three flagrant 1 fouls in a game, regardless of his overall foul count.
• Red and amber lights can now be placed on the backboard.
• Schools will no longer have to apply for a waiver to allow players to use religious headwear that is safe for competition.
• All numbers from 0–99 will be allowed. Previously, player numbers could only include digits from 0 to 5.
• Conferences will be allowed to continue using an experimental rule that allows for media timeouts to be taken at the first dead ball after the 17-, 14-, 11-, 8-, and 4-minute marks of the second half. This rule may also be used in the 2024 NIT, subject to approval by the NCAA's NIT board.
• Also, subject to NIT board approval, the free-throw lane may be widened to 16 feet in the 2024 NIT.

The IUPUI athletic program will be transferred to the new IU Indianapolis, maintaining IUPUI's memberships in Division I and the Horizon League.[19]
