Cal running back Jahvid Best missed practice Wednesday with what doctors told him was a "mild concussion," but Best anticipates playing Saturday against Oregon State. Best sustained his injury Saturday against Arizona State, though he wasn't diagnosed with a concussion until Monday. He downplayed the symptoms, saying it "felt like a headache to me," but Cal kept him out of practice the past two days. Tight end out: Anthony Miller, the Bears' starting tight end and third-leading receiver with 17 catches, had arthroscopic knee surgery Tuesday to repair meniscus damage in the knee, coach Jeff Tedford said. Tedford wasn't sure if Miller will recover in time to play Nov. 14. Skylar Curran will replace Miller as the starter Saturday. Briefly: Guard Matt Summers-Gavin and nose guard Derrick Hill, both of whom missed the ASU game with shoulder injuries, are considered doubtful for Saturday.
