SAN FRANCISCO –- Tight end Vernon Davis was ruled out Sunday's game late in the first half after sustaining a concussion.

Davis was evaluated in the 49ers' locker room and diagnosed with a concussion. He must pass the NFL’s protocol on concussions to be cleared to play next Sunday against the New Orleans Saints.

Davis appeared to sustain the injury when his helmet struck the ground after Panthers safety Mike Mitchell stripped him of the ball on a Colin Kaepernick pass attempt. The play was ruled an incomplete pass.

Davis was forced out of a game last season against the Seattle Seahawks with a concussion on Dec. 23 when he was struck by Kam Chancellor. Davis returned to action the following week for the 49ers’ regular-season finale.

Davis had one catch for 2 yards in the first half Sunday against the Panthers. He ranks second on the 49ers with 30 receptions for 520 yards and seven touchdowns.

With Davis out of action, the 49ers went with rookie tight end Vance McDonald at tight end.
