The Washington Redskins came out relatively clean in terms of injuries, following their 20-10 win Thursday over the New York Giants.

Now as the Redskins shift their attention toward the Dallas Cowboys, the question becomes when their players dealing with existing injuries can return. On the latter, Redskins coach Jay Gruden isn’t so sure.

Gruden said Friday that he has “no idea” when Jordan Reed will return. The athletic tight end has missed the last four games with a hamstring strain.

“The issue is, when he does come back, we’ve got to make sure that he’s 100 percent so this thing doesn’t linger,” Gruden said. “So I don’t know if he’ll be back this week, the next week or four weeks. We have no idea right now. I think that’s between he and the trainers. He’s got to get some work in and when he’s ready, we will definitely utilize him.”

If healthy, Reed would play a pivotal role for the Redskins in the final five games of the season. Reed’s athleticism and size would give quarterback Kirk Cousins another explosive receiver, and would be perhaps Washington’s top option.
