Hold on to your seats, there's breaking news on the Penn State football front.

The offensive line is changing — again. Just when there seemed to be no remaining combinations, it got a new look.

During the bye week, coach Joe Paterno reassessed his sputtering offense. And once again, he had a new set of adverse circumstances to deal with — injuries.

"We worked fairly hard last week," Paterno said. "Unfortunately, we literally have to start all over because Jordan Caruso got hurt."

Caruso, a senior offensive lineman, almost completely tore the medial collateral ligament in his left knee. He'll be sidelined for at least three weeks.

Center Matt Schmitt was moved out of the starting rotation because of a strained hip flexor, which means Eric Rickenbach gets the nod.

But there is good news when it comes to injury. Offensive lineman Gus Felder has been released from the confines of the injured list after spraining a medial collateral ligament before the Ohio State matchup.

Felder, a junior, was upset at the poor timing of the injury. But after a few weeks of catching up on schoolwork and studying tape, Felder said he feels 100 percent.

"I was upset because I missed three big games," Felder said. "I haven't played in the Big Ten and I really wanted to."

Senior Kareem McKenzie, junior Joe Hartings and senior Imani Bell round out the rest of the starting lineup.

For Paterno, the weekly game of mix and match could be avoided — if there were no injuries. The coach knows he must keep one group together each week, but it's out of his hands.

Bell agreed and said it's difficult to block when there's new people blocking beside each other every week.

"If there weren't any injuries on the line," Bell said, "there would be a lot more consistency. I just think I am fortunate not to be injured."

The holes in the line left room for reserves, including freshman Chris McKelvy. Paterno said he was hoping not to throw a freshman into the lineup against Illinois, but injuries dictated otherwise.

"I like McKelvy," Paterno said. "He is a smart, solid and strong kid. I think that eventually he is going to be a good tackle."

Teammates said McKelvy has been fighting nerves, but has had solid practices.

"He's a hard worker and a good player," Felder said. "If he relaxes, doesn't worry about mistakes he makes and uses his God-given ability, he'll be fine."

Which is what Paterno hopes for his entire offensive line.
