Washington coach Jay Gruden selected Jackson, along with linebacker Perry Riley Jr., as a captain for Sunday's game.
Jackson was limited Friday, which is what the Redskins expected he would be, but did participate in individual drills.
During that time Jackson had to occasionally raise his sprained left shoulder above his head to make a catch. He did not appear 100 percent fluid with his shoulder but he was able to catch the ball.
Jackson was cut in the offseason by Philadelphia despite being one of the NFL's top receivers and kick returners during six seasons with the team.
Minus Reed, the Redskins will again use tight end Niles Paul. In two games, he's caught 12 passes for 185 yards. That matches Paul's total number of catches from the past two seasons.
