No. 17 Iowa beat No. 18 Michigan 20-19 on the final play Saturday at Michigan Stadium, ending a Wolverines lead that held for most of the afternoon and handing Michigan its first Big Ten loss.

Hank Brown threw a 16-yard touchdown pass to Reece Vander Zee as time expired, capping a 91-yard drive aided by an unnecessary roughness penalty on Michigan and a 29-yard completion to Addison Ostrenga, NBC Sports and Michigan Athletics reported. Attendance was 111,126. Bryce Underwood threw two touchdown passes to JJ Buchanan, including a 49-yard strike that briefly restored a 19-14 Michigan lead in the fourth after Braeden Jackson's 99-yard kickoff return had answered an earlier Iowa score. Trey Butkowski added field goals from 41 and 22 yards. Iowa improved to 4-0 (1-0 Big Ten); Michigan fell to 3-1 (0-1).

The hangover is ranking and résumé math as much as the final snap. Iowa hosts No. 7 Ohio State next Saturday. Michigan travels to Minnesota for an 11 a.m. CT kickoff on Fox — its first road game of the season. Michigan had won 47 straight when leading at halftime, the longest active FBS streak, before Saturday's collapse, NBC Sports noted. Michigan Athletics also flagged two red-zone turnovers that kept points off the board despite 429 yards of offense to Iowa's 285.
