from www.fanball.com The News The 49ers won't have Alex Smith under center for a long time. The quarterback told the San Francisco Chronicle that he expects to miss "several weeks" with the Grade 3 separation of his throwing shoulder that he suffered on Sunday. No surgery is planned right now, but the team will know more about his condition on Thursday. Our View Trent Dilfer will start in Smith's place, and that is bad news for an already shaky passing attack. Dilfer managed only 128 yards and threw a pair of picks against the Seahawks, and things won't be any easier this week against the Ravens.
