Wilfork, a key cog in the 3-4 defense at nose tackle, hurt his foot in last Sunday's 20-10 win over the Panthers. He returned for one play in the second half before leaving the field in pain, throwing his helmet to the ground.
Warren has been playing through an ankle injury, which he apparently re-aggravated last Sunday. He was hurt early in the fourth quarter and did not return.
This is a significant blow for the Patriots, although it could be lessened by the fact the Bills have a shaky situation on their offensive line.
Injured Wilfork, Warren won't play Sunday in Buffalo.
