Iowa No. 17 stunned No. 18 Michigan 20-19 after quarterback Hank Brown threw a 16-yard touchdown pass to Reece Vander Zee as time expired. The victory mattered as a significant Big Ten upset and capped a dramatic final drive, while recalling recent controversy at the same stadium over an extra second being added to the clock in Michigan’s win over Western Michigan.

Iowa covered 91 yards on the decisive possession, benefiting from a Michigan unnecessary-roughness penalty and a 29-yard completion to Addison Ostrenga. Michigan quarterback Bryce Underwood threw two touchdown passes to JJ Buchanan, including a 49-yarder that put the Wolverines 19-14 ahead, but Michigan could not close out the game; both teams entered ranked in the top 20, with Michigan falling to 3-1 and 0-1 in conference play.
