The Buffalo Bills lost two key players on Sunday, according to ESPN.com.

Receiver Roscoe Parrish suffered an ankle injury in Buffalo's 38-35 victory over the Oakland Raiders and is out indefinitely. Also, starting right guard Kraig Urbik will miss several weeks with a knee injury.

The Bills are off to surprising 2-0 start after rallying late to knock off the Raiders, but now will have their depth tested with the injuries.
