Swanigan was hurt on Sunday in the first half at Iowa. He wound up playing 25 minutes but finished just 2 for 9 from the floor. Coach Matt Painter said afterward that Swanigan's ankle was ''fine,'' but the 21st-ranked Boilermakers apparently weren't ready to risk aggravation for their freshman standout.
Purdue went with a smaller lineup against the Gophers, with Dakota Mathias and P.J. Thompson starting in place of Swanigan and Johnny Hill from the last game. The 6-foot-9 Swanigan is averaging 10.1 points and 8.9 rebounds per game.
