The Cowboys promoted cornerback Vince Agnew from the practice squad Saturday in case Mike Jenkins can't play Sunday. Jenkins is questionable after leaving Thursday's practice with back spasms. He did not practice Friday.
Agnew was signed to the practice squad Oct. 16. He has never played in a regular-season NFL game.
To make room for Agnew on the 53-player roster, the Cowboys released linebacker Gary Guyton, who signed Wednesday. The Cowboys had signed Guyton because of a string of injuries at the inside linebacker position. Sean Lee is on injured reserve with a foot injury; Orie Lemon is on injured reserve with a hamstring injury; and Dan Connor is doubtful for Sunday's game because of a neck injury.
