Alex Smith went through his second straight practice wearing a black, no-contact jersey, an indication that he hasn't yet been fully cleared after his Sunday concussion.
As was the case on Wednesday, Smith began practice -- the first 20 minutes or so are open to reporters -- like he has every other session. He took snaps alongside backup Colin Kaepernick, handing the ball to Frank Gore and the team's other running backs and throwing passes to the wideouts.
The last stage following a concussion is to be cleared for a contact practice. Smith noted the absurdness of that given that quarterbacks don't receive any contact in practice even when fully healthy.
"Had the black jersey on me, which is a little redundant, seeing as how we don't get hit in practice," Smith said on Wednesday. He was not available to the media today.
The 49ers listed both Smith and cornerback Chris Culliver (shoulder) as limited participants in practice on today's injury report. EVeryone else listed practiced in full. They are:
RB Anthony Dixon (hamstring), S Dashon Goldson (ribs), LB Tavares Gooden (elbow, quadricep), C Jonathan Goodwin (ankle), RB Frank Gore (ribs, wrist), G Mike Iupati (quadricep), WR Mario Manningham (shoulder), DT Will Tukuafu (wrist), LB Patrick Willis (shoulder).
Dixon, Goldson, Gooden's quadriceps, Gore's ribs and Iupati are new additions from last week's report.
For the Bears, meanwhile, quarterback Jay Cutler (concussion) did not practice.
