49ers GM John Lynch called RB Elijah Mitchell (shoulder) "very questionable" for Sunday night's game against the Packers. We'll see if Mitchell does anything in practice later today -- and then how he's listed on the final injury report. RB Trey Sermon's Week 3 status is also up in the air with his concussion. Trenton Cannon and Jacques Patrick are the only healthy RBs on San Francisco's active roster. RB Kerryon Johnson is a potential practice-squad callup.
