Chuck Long completed 14 of 20 passes for 146 yards and Devon Mitchell set up two scores with interceptions to help 18th-ranked Iowa give Michigan the worst defeat in the 16 years it has been coached by Bo Schembechler, a 26-0 loss yesterday in Iowa City.
It was the first time Michigan was shut out since 1977 and the third consecutive Big Ten game the Hawkeyes' defense did not allow a touchdown. The last time Iowa shut out Michigan was a 0-0 tie in 1929.
Long, Ronnie Harmon and Owen Gill each ran for a touchdown and Tommy Nichol kicked two field goals for Iowa (5-2, 4-1 in the Big Ten). The Wolverines, who hadn't lost in Iowa City since 1962, are 4-3, 3-2.
Trailing, 12-0, late in the third quarter, Michigan moved to the five-yard line. On third down, Mitchell intercepted Russ Rein's pass at the one and returned it 75 yards. Five plays later, Gill ran nine yards for a touchdown to make it 19-0.
Gill carried 16 times for 85 yards to become Iowa's second all-time leading rusher with 2,150 yards, 27 from the school record. Harmon, who started the game as the No. 2 all-purpose runner in the nation, gained 63 yards.
"We ran a lot when they thought we'd throw and we threw a lot when they thought we'd run," Coach Hayden Fry said. "I wish we had a picture of all the eyes keying on Harmon."
