Anthony Davis still dealing with concussion symptoms, according to Jim Harbaugh

San Francisco 49ers head coach Jim Harbaugh met with the media today, and he told them he believes right tackle Anthony Davis is still dealing with concussion symptoms. He said Davis's availability was up in the air.

The 49ers face the Seattle Seahawks on Thursday, so he will need to get back on the practice field sooner rather than later. They likely will not have a normal practice session today, but even if that happens, there will be a practice report listing what they would be listed as if there had been a practice session. The 49ers will have fairly regular practice sessions on Tuesday and Wednesday, so those will be the reports to track.

If he does not play, Jonathan Martin will get the start. Martin allowed a sack and two hurries, and finished with a -2.3 overall grade. His pass block grade was -1.3, and his run block grade was -1.2. People have suggested moving Joe Looney in at guard, and swinging Alex Boone out to right tackle, but I doubt anything like that happens Thursday, or even the rest of the year.
