==== An NCAA committee has approved three rules changes intended to clarify block-charge calls, who can shoot free throws after an injury and the expanded use of replay.The announcement Monday means secondary defenders must establish position outside the area between the backboard and the front of the rim to draw a charge call.The panel also addressed the perceived advantage teams had when a fouled player is injured. Previously, the shooting team's coach could select any player on his roster to take the free throws. Now, the opposing coach must select from the four players remaining players on the court.And the committee approved expanding replay to determine flagrant fouls, which would result in ejection.The rules changes will go into effect this fall.====
