Wilfork suffered the injury during the game's opening drive. The Associated Press originally reported Wilfork had suffered an ankle injury.
Wilfork, a five-time Pro Bowl selection, appeared to turn his right foot while trying to pressure quarterback Matt Ryan from the New England 6-yard line.
Rookie Joe Vellano, who sacked Ryan for a 13-yard loss late in the third quarter, took some snaps in Wilfork's spot after the injury.
Information from the Associated Press was used in this report.
