Indiana postponed Tuesday night's basketball game against No. 15 Iowa after piece of metal fell into the seats at Assembly Hall about six hours before tipoff.
Athletic director Fred Glass said the school made the decision after the metal piece, roughly 8 feet long and 14 inches wide, fell into the lower bowl of the arena and damaged seats in the northwest corner.
The game was scheduled for 9 p.m. and a makeup date was not announced.
Glass said the school made the decision for the safety of fans and that no decision had been made about whether to play Wednesday night's women's game against Michigan.
Assembly Hall opened during the 1971-72 season and holds more than 17,000 fans.
A multimillion-dollar renovation plan is in the works.
