Herron's heroics boost Wolverines' defense

ANN ARBOR, Mich. -- Can one play change a unit's fortunes? We'll soon find out.

Linebacker Brandon Herron boosted the Michigan defense with a 94-yard interception return off of a pass tipped by freshman linebacker Jake Ryan. It's the longest interception return for a touchdown in modern Michigan football history (post-World War II).

The Wolverines' defense looked very vulnerable until Herron's pick-six, as Western Michigan was moving the ball well for the third consecutive possession and had second-and-goal. Making matters worse, top Michigan cornerback Troy Woolfolk suffered a leg injury on kickoff coverage. Woolfolk, who missed all of the 2010 season with a dislocated ankle and a broken leg, left the field on his own power but had to be carted to the locker room. No word yet on the extent of his injury, but it didn't look good.

Michigan carried over the momentum, stuffing Western Michigan on the Broncos' ensuing possession.

Can the Wolverines keep it up? They lead 14-7 midway through the second quarter.
