Wisconsin will be without one of its top defensive players again this Saturday as Michigan comes to Madison.

Jeff Potrykus of the Journal-Sentinel tweeted out Monday morning that linebacker Chris Orr would miss this weekend’s game against the Wolverines. This would be the second-straight game he has missed, as he didn’t play vs. Iowa, either.

Orr suffered an injury to his left leg in Wisconsin’s game against Indiana in Bloomington. He was hurt in the first quarter and hasn’t seen the field since. While it hasn’t negatively affected the Badgers on the field yet, his absence is huge against Michigan.

In nine games, Orr has racked up 35 tackles, including three stops for loss and two sacks. He’s also had one interception this season. He had been an anchor on a defense that was already riddled with injuries.

Wisconsin is putting its undefeated 10-0 record on the line this weekend against the Wolverines. Both teams bring excellent defenses to the field, as the Badgers rank first in total defense and Michigan ranks second.

Saturday’s game is scheduled to kickoff at noon ET and will air on FOX. ESPN’s College GameDay will also be in Madison for the match-up.
