Phillip Welch made a 28-yard field goal moments into the second quarter, giving Wisconsin a 10-7 lead against Indiana.
The Hoosiers took advantage of a Badgers' mistake on special teams for their touchdown. David Gilreath fumbled a punt by IU's Chris Hagerup. Collin Taylor recovered for IU at Wisconsin's 10. Two plays later, Ben Chappell rolled to his left and completed an 11-yard touchdown to Tandon Doss.
John Clay went 48 yards on the first rushing play for Wisconsin in the next drive. That set up an 18-yard touchdown pass from Scott Tolzien to Isaac Anderson.
The Badgers reached IU's 1 in their next possession. But an offensive pass interference penalty pushed them back to 20, and they eventually had to settle for the field goal.
Clay has 63 rushing yards for Wisconsin. Chappell went 5 for 5 passing in the first quarter for 30 yards.
