"He was able to get through everything," Eagles coach Andy Reid said. "It looked like he did it well. We will just see how he feels later today and then tomorrow. Most importantly, we'll see how he feels on Sunday."
Westbrook is questionable on the injury report, but has been able to participate more in practice as the week progressed.
The All-Pro running back would give the Eagles a big lift against Washington in a division showdown in the tough NFC East.
Since Westbrook went down in the first half of a 15-6 win over the Pittsburgh Steelers in Week 3, the Philadelphia offense has been erratic.
Last week in a 24-20 loss to Chicago, the Eagles were able to put up points in the first half but struggled late in the game -- especially in the closing minutes when they turned over the ball on downs after taking three shots at the end zone from the Bears 1-yard line.
Getting back Westbrook, who led the league with 2,104 yards from scrimmage and caught 90 passes last season, would be a big boost to the Eagles. Westbrook had five touchdowns as the Eagles scored 75 points in the first two weeks.
Tight end L.J. Smith, who also missed the Chicago game, is listed as questionable but seems likely to play after practicing all week. Receiver Kevin Curtis (sports hernia), defensive end Victor Abiamiri (wrist) and two-time Pro Bowl guard Shawn Andrews (back) are doubtful.
Quarterback Donovan McNabb, who played through a chest contusion last week, is still working through the injury, Reid said.
"He's still a little sore," Reid said. "But he worked through it and felt pretty good today."
