USC's starting left guard, Chris Brymer, tested his broken foot for the first time in more than a month and said it "feels great" after running at half-speed for about 20 minutes.
Trainers told Brymer a key would be how much pain he has this morning. If he's relatively pain-free, he's to run again Tuesday.
Brymer was injured Sept. 14 against Oregon State.
Starting defensive end Willie Lowery, who sprained an ankle in the 14-7 victory over Arizona Saturday, won't practice until Tuesday. He is questionable for Arizona State.
