The Redskins listed Reed as inactive Monday night for their game against the Seattle Seahawks.
Reed hasn't played since the season opener, when he pulled his left hamstring. He returned to practice on a limited basis last week and was listed as questionable for the game.
Other players the Redskins had listed as questionable were active, including left tackle Trent Williams and tight end Niles Paul. Williams has a sore right knee, and Paul has recovered from a concussion.
The most notable name on Seattle's inactive list was tight end Zach Miller, who is expected to miss at least two games while recovering from ankle surgery.
