"I couldn't answer that if I wanted to," Alvarez said. "Ankles are very fickle. Anthony was ready to go and he played. You tweak it the right away, you get hit on it, you plant the wrong way and lose strength in it. I don't think Dwayne's was as bad as Anthony's and it might not even have been an ankle, it might have been more of a foot. You just don't know. You don't know what to expect."
Davis originally injured his ankle at the end of ten yard run early in Wisconsin's contest with UNLV. He missed the following two weeks but started against Penn State Saturday. Davis, though, re-injured the ankle in the first half and finished with eight carries for 35 yards.
Smith suffered his injury early in the third quarter against Penn State. Two weeks earlier, Smith missed the second half against North Carolina with a strained groin. He returned to action the following week against Illinois and tallied 193 yards rushing and three touchdowns. He currently leads the team with 86 rushing attempts and 467 yards.
If Davis and Smith cannot play or are limited by their injuries against Ohio State, the team will again turn to redshirt freshman Booker Stanley who has rushed 73 times for 329 yards and four touchdowns this season.
Davis, who ran for more the 3,000 yards over the course of his freshman and sophomore seasons, has 460 yards and four touchdowns on 69 carries. He and Smith each have four rushing touchdowns this year.
