Jim Harbaugh nearly combusted following a flag on James Ross.

The Michigan linebacker took down Mitch Leidner and pulled him across his body to the ground. Originally, an unsportsmanlike penalty was ruled.

Instead of giving Minnesota an automatic first down, it gave the ball back to Michigan to take the lead.
