Wolff left last Sunday's 27-13 victory at Green Bay with a knee injury. Veteran Patrick Chung, who was rotating with Wolff and Nate Allen at the safety positions, will start.
Inside linebacker Mychal Kendricks (knee), cornerback Bradley Fletcher (pectoral) and left tackle Jason Peters (quad) are questionable for the matchup with the Redskins.
Fletcher was injured during Philadelphia's 49-20 victory at Oakland on Nov. 3. He was listed as questionable for last weekend's game and did not play.
Fletcher was replaced by Roc Carmichael, who could start again as the Eagles try for their third consecutive win.
