ORCHARD PARK, N.Y. (AP) -- Buffalo Bills starting linebacker Chris Kelsay's calf injury will keep him out of Sunday's game against the Philadelphia Eagles (1-3), and it could keep him sidelined for an extended period of time.
Kelsay was injured during Thursday's practice, and coach Chan Gailey said Friday Kelsay would be "out for a little while."
Starting cornerback Terrence McGee (hamstring) is expected to play after missing the past three games. His return would bolster a depleted Bills defensive backfield against an Eagles explosive offense led by quarterback Michael Vick.
Rookie cornerback Aaron Williams will miss his second straight game because of a chest injury for the Bills (3-1).
