All but eliminated from playoff contention at 5-7 with four games left, the Washington Redskins will need to consider whether they should place certain players battling significant injuries on injured reserve. During Friday's conference call,coach Jay Gruden said each player will be evaluated on a case-by-case basis. "I think if they're good enough to go, they need to go," Gruden said. "But we'll see how they're doing from a longevity standpoint. We obviously don't want to hurt anybody's future and a chance for them to injury themselves long-term. But if it's just a nagging ankle sprain or something like that where the guys can play through it, then they'll play through it." Gruden was later specifically asked about left tackle Trent Williams, who has played through a right knee injury since Week 4. "Let's find out what the timeline is for the surgery — if he has to have surgery number one, what type of surgery it's going to be and how long it's going to put him out," Gruden said. "We'll go by what the doctors say, how Trent feels and make our decision with Trent." Gruden said the same process applies for tight end Jordan Reed, who has missed the past five games because of a hamstring injury. Reed has played in just six games in a season in which he opened training camp on the physically unable to perform list.
