The game originally was slated for last week but was postponed after an 8-foot, 50-pound steel plate fell from the ceiling of Assembly Hall about 6½ hours before the scheduled start.
The plate was reinforced with four additional bolts, Indiana athletic director Fred Glass said before Thursday's tipoff.
Three other steel plates were found to be loose and those were taken down, inspected, and reinforced to the ceiling with additional bolts as well, Glass said.
Melting snow and ice pushed water behind the steel plate, jarring it loose. Glass said the tops of the plates were shaved off, allowing more room between the ceiling and the plate itself.
The Hawkeyes had a chance to move up in the league standings with No. 22 Ohio State's 65-63 loss at Penn State on Thursday night, and they closed the first half on a 9-0 run. Zach McCabe hit a 3-pointer and White dunked twice, including one with 1:16 left to put Iowa ahead 50-49.
