COLUMBUS, Ohio (AP) — Ohio State coach Jim Tressel said Thursday it is doubtful that starting tailback Chris "Beanie" Wells will play Saturday night against No. 1 Southern California.

Tressel said there was lingering soreness for Wells in his right foot after he worked out Wednesday night. Wells didn't practice with the team Thursday morning just before it departed for Los Angeles.

"We were hoping he'd wake up this morning and feel even better than yesterday," Tressel said shortly before boarding the team bus to the airport. "But it didn't happen. We'll see from here."

Wells injured his right foot in the fifth-ranked Buckeyes' opener.

against Youngstown State, didn't play last week against Ohio and hasn't had contact in partial practices this week. He flew with the team Thursday afternoon.

Tressel didn't rule out the possibility of the junior seeing action, but didn't sound optimistic.

"Beanie practiced about 20 carries yesterday, and maybe 20 percent of the practice," Tressel said. "We didn't have him work today. He had more soreness this morning than we had hoped for. A late afternoon practice followed by a morning practice, we're hoping that's a little bit of the reason why. So we'll just have to play it by ear."
