Central Michigan's David Harman drilled a 47-yard field goal with :03 left and the Chippewas scored nine points in the final :45 to stun host Iowa 32-31 on Saturday afternoon.
Central Michigan (2-1) pulled to within 31-29 on Ryan Radcliff's 13-yard TD throw to Titus Davis. The Chippewas failed on the two-point conversion, but they recovered an onside kick and moved to Iowa's 30-yard line in part because of a personal foul on the Hawkeyes (2-2).
Harman had the wind at his back on the winning kick, which handed Iowa one of its most improbable defeats in 14 years under coach Kirk Ferentz.
Mark Weisman ran for 217 yards and three touchdowns for Iowa.
