Iowa Stuns Michigan with Last-Second 91-Yard Drive Touchdown

ANN ARBOR, Mich. -- Hank Brown threw a game-ending, 16-yard touchdown pass to Reece Vander Zee to lift No. 17 Iowa to a 20-19 win over No. 18 Michigan on Saturday.

The Hawkeyes (4-0, 1-0 Big Ten) went 91 yards on the final drive -- boosted by an unnecessary roughness penalty against Michigan on a third down at midfield. Brown's 29-yard pass to Addison Ostrenga set up the final play with two seconds on the clock.

Bryce Underwood threw a 49-yard touchdown pass to JJ Buchanan early in the fourth quarter -- their second scoring connection of the game -- but the Wolverines (3-1, 0-1) could not make enough plays on both sides of the ball to hold on for the win.

Iowa took its first lead early in the fourth quarter on Brown's 16-yard touchdown pass to Vander Zee.

Then Underwood dropped back, stepped up, rolled right and threw a long touchdown pass to Buchanan for a 19-14 lead. His 2-point conversion pass fell incomplete.

Iowa lined up to go for it on fourth down at the Michigan 28 late in the game and left guard Leighton Jones was flagged for a false start. Facing a fourth-and-6, coach Kirk Ferentz chose to have Caden Buhr attempt a 51-yard field goal and it was wide right with 2:33 left to play.

Iowa's defense forced Michigan to punt again and its offense took advantage.

On Underwood's first touchdown pass to Buchanan, he converted a third-and-7 from the Iowa 18.

The lead didn't last long because Braeden Jackson , son of former NFL running back Fred Jackson, returned the ensuing kickoff 99 yards for a score.

The Wolverines went back ahead early in the second quarter on Trey Butkowski 's 41-yard field goal.

Instead of kicking another field goal later in the quarter, Kyle Whittingham went for it on fourth-and-1 from the Iowa 18 and Underwood's sneak was stopped.

Underwood was picked off Deshaun Lee , a former teammate at nearby Belleville High School, at the Iowa 2 early in the third quarter.
