Mario Ojemudia out for season with Achilles injury

Mike & Mike surprised by Michigan, Ohio State

Mike Greenberg and Mike Golic share their thoughts on a couple of their shocking storylines in college football one month into the season.

ANN ARBOR, Mich. -- Michigan senior Mario Ojemudia suffered an Achilles injury over the weekend that will end his season and college career, coach Jim Harbaugh said Monday.

Ojemudia was in the midst of a breakout season as the rush linebacker for a unit that is ranked second in the nation in scoring defense. He is currently third on the team with 19 tackles and produced six tackles for loss and two sacks in the first five games of the season.

The Detroit-area native played during his first three seasons and is far enough into his senior year that he won't be able to preserve a year of eligibility.

The Wolverines will likely turn to senior Royce Jenkins-Stone and sophomore Lawrence Marshall to replace Ojemudia.

"We'll look within our roster and our defense. I don't know exactly who yet, but it'll be one of those guys," Harbaugh said.

Michigan faces Northwestern and the nation's No. 1 scoring defense at Michigan Stadium on Saturday.
