Zack Mills stood on the sideline wearing a head set for most of the last three games.

That might all change on Saturday.

Penn State football coach Joe Paterno refused to state the name of whom he would start against Iowa this Saturday.

He also wouldn't say if he would play both Mills and backup Michael Robinson.

"I don't spend nights worrying about it," Paterno said. "We'll wait and see how it plays out."

Robinson has started for the Nittany Lions against both Purdue and Wisconsin, as Mills was out with a sprained knee.

Paterno said that Mills hasn't practiced much during the team's off week. But he practiced Monday and expects him to practice the rest of the week.

Paterno said Mills isn't quite at 100 percent yet, but he should be by the time Penn State leaves for Iowa.

"He looked like a 100 percent for the first time yesterday," Paterno said. "He went through a couple tough drills."

Robinson is coming off the Purdue game 10 days ago when he struggled finding receivers and completed 10-of-32 passes. His lackluster effort came seven days after Robinson threw for 379 yards, in his first career start.

Linebacker Deryck Toles said that he didn't know who was going to start, but that it wasn't going to be him.

"I play defense," he said.

Back on the field

Paterno said that freshman running back Austin Scott practiced Monday. Paterno was waiting to see how the tailback was going to react to the workout.

The 76-year-old said that Scott would be in the mix against Iowa after not making the trip to West Lafayette, as he was suffering from mononucleosis.

But Paterno continues to support senior running back Ricky Upton.

"Upton isn't flashy," Paterno said. "But when he gets in there he gets the job done."

In Scott's absence against Purdue, fellow freshman Tony Hunt carried the load, rushing nine times for 47 yards.

Moving again

With Scott's illness, Paterno thought he might be a little bit short-handed at running back and moved Donnie Johnson from wide receiver back to tailback, where he started the season.

Johnson is currently splitting time between both running back and wide receiver. Paterno said that move was made as Scott could have been out three or four weeks.

Ahead no longer

Florida State football coach Bobby Bowden tied Paterno with 338 wins, with the Seminoles victory over Virginia Saturday night, 19-14.

"I have a doll in my room," Paterno said laughing. "I stick daggers in it."

But in reality, Paterno has the utmost respect for him saying, "Bobby Bowden is one heck of a guy."
