Michigan tight end Jake Butt has torn his ACL in winter conditioning. The sophomore was the second leading receiver at tight end for the Wolverines a year ago. He turned heads when he caught a late touchdown in the shootout with then undefeated Ohio State. He also had a score in the first overtime against Northwestern.
Unless things went very well for both schools, it was unlikely that Nebraska would have faced Michigan in 2014. The Wolverines could still play a spoiler role in games against Minnesota and Northwestern which could conceivably impact a the Western division race.
Most likely though, they'll be a footnote in terms of how things shake out in the West. Butt did not redshirt and could spend the next year and a half recuperating.
