ANN ARBOR, Mich. — No. 16 Michigan survived a stunning upset bid from Western Michigan on Saturday night, winning 13-12 on a dramatic 47-yard Hail Mary touchdown with the final second of the game.

Michigan appeared to have lost when quarterback Bryce Underwood’s first Hail Mary fell incomplete as the clock appeared to hit 0:00. Western Michigan players began celebrating what looked like a historic upset.

Officials then reviewed the play and restored one second to the clock.

According to the Big Ten’s explanation, Western Michigan’s No. 18 touched the ball while starting his jump from an established out-of-bounds position, and that contact occurred with one second remaining.

That gave Michigan one final opportunity.

Underwood took the snap and launched another Hail Mary from near midfield. JJ Buchanan came down with the 47-yard touchdown catch, sending Michigan Stadium into chaos and giving the Wolverines a 13-12 victory.

The controversial finish immediately sparked debate because television replays appeared to show the clock reaching zero before the ball was touched on the first attempt. The Big Ten later released an explanation and replay evidence supporting its ruling. The Mid-American Conference also accepted the Big Ten’s explanation.

Michigan avoided what would have been a massive upset in new head coach Kyle Whittingham’s debut, while Western Michigan was left heartbroken after coming within seconds of one of the biggest wins in program history.

Final: Michigan 13, Western Michigan 12.
