49ers vs. Seahawks injury report: Joe Staley upgraded to limited

In a moderately interesting twist, the 49ers have upgraded offensive tackle Joe Staley from not participating in practice to limited participation. It sounds like he and Mario Manningham (also listed as limited) were wearing black no-contact jerseys, but both got some practice participation in on Tuesday.

Staley suffered a concussion on Sunday against the Giants, but according to Staley, he is symptom free and ready to go. He has not yet been cleared by doctors, although I think we will get some information tomorrow. There are several tests that need to be passed, including at rest and after exertion.

"We're going through the process," Staley said. "We're going through a few different stages and I met with the neurologist yesterday. Everything went well there. And today, I have a workout, go on the field and see how everything goes with that."

We'll keep an eye out and hopefully get a final answer on Staley's status. While Alex Boone would seem to be a fine replacement at left tackle and Leonard Davis actually was relatively solid filling in for Boone at right guard, I'd much prefer the starting lineup in place. The 49ers are facing a tough Seahawks front seven and will need the line to bring their A-game on Thursday.
