Patriots NT Vince Wilfork exited Sunday night's Week 4 game against the Falcons with a right ankle injury. Wilfork has been dealing with the ankle/foot injury since last week and suffered a setback after having it stepped on in the first quarter. He was carted off the field and is questionable to return. His loss is a huge downgrade to the defensive line. The Patriots have just Tommy Kelly, Joe Vellano, and Chris Jones behind him on their 53-man roster.
