SANTA CLARA, Calif. (AP) - Vernon Davis is anxious to get back on the field with the San Francisco 49ers and help them build momentum for the playoffs during Sunday's regular-season finale against Arizona.

He still has to be cleared to play first.

Davis practiced in a non-contact black jersey for the second consecutive day Friday and is taking the necessary steps, according to NFL-mandated protocol, to return from a concussion he sustained during last week's loss to the Seattle Seahawks.

The 49ers have a pressing need for their starting tight end to return after the team placed starting receiver Mario Manningham on injured reserve early Friday, leaving San Francisco without its second-leading receiver for the rest of the season.
