SANTA CLARA, Calif. -- The San Francisco 49ers did not make a roster move Tuesday to adjust to the likely season-ending scapula injury suffered by versatile fullback Bruce Miller at Tampa Bay.However, there was no urgency to make a move. The 49ers host Atlanta on Monday night and their practice week doesn't start in earnest until Thursday. There is a chance they could make a move Wednesday.One option is former defensive lineman/fullback Will Tukuafu.
