The San Francisco 49ers picked up a pair of injuries in their 42-13 loss to the Seattle Seahawks. Starting tight end Vernon Davis left the game in the first half after a hit from Kam Chancellor. Davis suffered a concussion in the collision and did not return to the game. Wide receiver Mario Manningham suffered an apparent serious knee injury in the third quarter and had to be helped off the field.
