COLUMBUS, Ohio —Ohio State tailback Chris Wells did not practice with the second-ranked Buckeyes on Monday.
Wells, who injured his right foot in Saturday's 43-0 victory over Youngstown State, continued to wear a protective boot on his right foot.
He fell to the turf on a carry at the Penguins 2-yard line in the third quarter. After lying on the field in pain, he was helped off and then carted to the locker room. He returned to the bench to watch the final few minutes before cautiously walking back to the locker room.
X-rays after the game did not show any broken bones.
"He has been diligent in taking as many treatments as possible from our athletic trainers the past two days," Ohio State football information director Shelly Poe said in an e-mail late Monday afternoon. "Other than that, (there is) nothing definitive to report on his diagnosis or prognosis timeline."
The Buckeyes play Ohio on Saturday, then travel to No. 3 USC in two weeks.
