ORCHARD PARK, N.Y. (AP) -- Denver Broncos safety Brian Dawkins left Saturday's game at Buffalo with a neck injury, and the team announced he wouldn't return.
Dawkins missed last weekend's game against New England with the same injury, and he aggravated it during the first quarter against the Bills.
Bills center Kraig Urbik also left with a right knee injury.
Urbik walked off the field early in the second quarter after getting hurt during Buffalo's final possession of the first quarter. He was replaced by Colin Brown.
Brown became the fourth center that Buffalo has used this season after starter Eric Wood sustained a season-ending knee injury in a 44-7 loss at Dallas on November 13.
