USC has lost junior forward Bennie Boatwright for the rest of the season with a knee injury. Boatwright, who was averaging 13.6 points and 6.4 rebounds per game -- both second on the Trojans -- suffered a left patella injury during Thursday's win over Oregon. The school said he'll be sidelined for several months, but that surgery isn't expected. USC is 18-9 overall and tied for second with UCLA in the Pac-12 with a 9-5 record. The Trojans, are considered an NCAA tournament bubble team and are a No. 12 seed in Joe Lunardi's latest bracket projections. USC has four regular-season games left, beginning with Saturday's home contest against Oregon State.
