Clark sustained an apparent concussion in the third quarter of last Saturday's win against No. 12 Ohio State. He remained in the game for several plays but did not come out for the next offensive series. Backup Pat Devlin led Penn State on its final two scoring drives.
Clark sat out practice Monday but is expected to do some running at today's workout. Head coach Joe Paterno will spend much of the week evaluating Devlin and third-stringer Paul Cianciolo.
"The other kids can use the work, and I think we will use them, practice them," Paterno said. "But everybody seems optimistic he is going to be fine."
Clark is among the 13 semifinalists for the Davey O'Brien Award.
Also, Paterno will have his injured hip examined by doctors this week, most likely Wednesday. He hopes to receive any necessary treatment, including surgery, immediately after the season so he can "get on the road and go out and recruit."
In other words, Paterno has no plans to step down after the season.
"They might say, 'Hey, let's go in there and fix it up, it needs to be fixed up,'" Paterno said. "And, obviously, it would be my option as to what the alternative may be. If it meant I didn't have to have an operation and I can do what I've been doing -- I've operated fairly well, really, you know. Obviously, I don't run around on the practice field, and I've been upstairs because I've not wanted to be a distraction on the sideline.
"I really honestly don't know what I'm going to do."
