LOS ANGELES (AP)
He got hurt in the Trojans' win over Washington on Sunday.
Stewart is averaging 3.6 points and 1.9 rebounds in 16 games this season. He worked his way into the rotation since Bob Cantu took over as interim coach on Jan. 14, scoring 31 points in the last seven games after scoring 26 points in USC's first 17 games.
