And Lee said that he would return from knee injury to play.
But USC interim Coach Ed Orgeron would not say definitively that the junior would be available.
"I don't know," Orgeron said Wednesday. "It looked good [Tuesday]. Knowing him, he's going to try to play, but I don't know if he's going to be ready. But it's only Wednesday."
Linebacker Morgan Breslin, who has been sidelined because of a hip injury, practiced Wednesday.
"We'll see how he feels tomorrow, but I really feel like he should play," Orgeron said.
Tailback Tre Madden continues to nurse a hamstring injury.
"We're not for certain there," Orgeron said of Madden's status for Notre Dame. "But it's a long time till Saturday."
