Rookie safety Earl Wolff, who aggravated a knee injury in Sunday night's win over the Bears, was a full participant at Eagles practice on Wednesday.
Wolff dinged the knee breaking up a pass in the 54-11 win. It was his first game back from a four-game absence.
Fellow safety Kurt Coleman, who missed the Bears game with a hamstring injury, also practiced in full.
The only two Eagles unable to practice Wednesday were safety/special teams ace Colt Anderson (knee) and guard Julian Vandervelde (back).
The Eagles face the Cowboys Sunday night at AT&T Stadium in Arlington, Texas in a de facto NFC East Championship Game. On Monday it was reported that Cowboys QB Tony Romo would miss the game with a back injury, but head coach Jason Garrett reiterated on Wednesday that Romo has not yet been ruled out.
