(CBS) Bears tackle Jermon Bushrod and linebacker Pernell McPhee will both play Monday in San Diego, while starting center Hroniss Grasu and linebacker Shea McClellin were ruled out.

It’s likely that Charles Leno will continue to start in Bushrod’s place at left tackle. Bushrod hasn’t played since Chicago’s loss in Seattle in Week 3. McClellin will miss his third straight game as he recovers from an ankle injury.
