An NCAA men's basketball rules committee announced three changes that will go into effect this fall.

One move clarifies charging calls, another determines who can shoot free throws after an injury, and a third allows expanded use of replay.

The change in charging calls is designed to reduce contact under the basket.

The second change addresses the perceived advantage teams can get when a fouled player is injured. Previously, the shooting team's coach could pick any player on his roster to take free throws. Now, the opposing coach must select from the four players still on the court.

The panel also approved expanding replay to determine flagrant fouls, which would result in ejection. That change also will apply to the women's game.
