Surrounded by microphones and recorders, Penn State defensive coordinator Ted Roof stared into the distance as if in a daze. Tears welled up in Roof's eyes when the subject turned to injured senior Michael Mauti.

The fiery Mauti is so much more than a linebacker to the Nittany Lions.

Mauti hurt his left knee in the first quarter of Saturday's 45-22 win over Indiana.

The team is expected to have more details in the coming days. But from the forlorn looks on the faces of some Nittany Lions, it's clear there are fears Mauti may not be able to play in the season finale next week against Wisconsin.

Mauti took a lead role in the offseason in helping keep most of the team together after NCAA sanctions were announced.
