FOX has reported that San Francisco 49ers tight end Vernon Davis is out for the rest of the game with a concussion.

Davis left the field before the end of the first half after what appeared to be a fumble, but was officially called an incomplete pass after a review. Davis' head hit the turf during the play.

Davis leads the 49ers in receiving touchdowns this season and is a huge loss for the 49ers, who are currently struggling to pass the ball against the Carolina Panthers.
