The San Francisco 49ers are back at practice on Thursday, and the latest news suggests offensive lineman Anthony Davis will not be available on Sunday against the Seattle Seahawks. Chip Kelly said Davis has not advanced far enough in the concussion protocol to even wear the blue non-contact jersey.
Davis is in the concussion protocol due to a concussion sustained in practice last Thursday. Each team is allowed one padded contact practice per week, and that is when the concussion happened. The concussion protocol requires a player be asymptomatic while at rest before he can begin considering football activities. The fact that Davis cannot yet wear the blue non-contact jersey suggests he is not fully asymptomatic.
Davis could clear up today and practice tomorrow, but based on the timing of it, my guess is he ends up inactive vs. the Seahawks. We can thus expect Marcus Martin to be joined by one of two rookies active on the offensive line. Last week, first round pick Joshua Garnett was available, with Zane Beadles serving as the swing tackle. The other option is fifth round pick John Theus potentially securing the swing tackle role. My guess is it is the former, but the latter could develop at some point.
