The Redskins placed tight end Jordan Reed on injured reserve, the team announced on Saturday.
Reed suffered a concussion in Washington's third preseason game this summer after a helmet-to-helmet hit by Falcons safety Keanu Neal. The tight end has yet to play during the regular season and has not practiced since Week 2.
ESPN's Adam Schefter reported last month that Reed's NFL career is "in jeopardy" due to the multiple concussions he has suffered throughout his years in the league. Though the exact number of concussions Reed has suffered is unknown, the Redskins reportedly believed Reed would put himself at grave risk by playing again.
Selected in the third round of the 2013 draft, Reed had a breakout season in 2015, catching 87 passes for 952 yards and 11 touchdowns in 14 games.
