Watch: Hoke, Mattison quarrel on sideline

Michigan's offense continues to spin its wheels this season, and things aren't peaceful for the Wolverines' defense, either.

Late in the first half of Saturday's game against Utah, Michigan defensive end Frank Clark sacked Utah's Kendal Thompson for a 13-yard loss. But the big play was somewhat mitigated by a 5-yard sideline interference penalty on the Wolverines.

Apparently, Mattison was at fault as cameras caught Hoke admonishing the veteran defensive coordinator to "get off the f---ing field." Mattison didn't take kindly to the rebuke and fired back at his boss.

Fun times in Ann Arbor.
