With the Washington Redskins potentially needing assistance at the center position with Spencer Long’s status uncertain for Sunday’s game against the Philadelphia Eagles, the team announced on Wednesday that Kory Lichtensteiger has been designated for return.

Lichtensteiger, who was placed on Injured Reserve in September with a calf injury, has a 21-day practice period for the team to evaluate his potential return to the active roster.

But with the Redskins allowed to designate only one player for return in a given season, the decision officially rules out a return for 2016 first-round pick Josh Doctson, who has been dealing with an Achilles injury since the summer months.

“It is disappointing for all of us,” Redskins head coach Jay Gruden said. “You know, we had high hopes for him coming out of TCU and the talent that he has and he’s disappointed but these things happen. There’s been a lot – if you look around the league, there’s a lot of first-rounders that didn’t get up and running this year for whatever reason and a lot of draft picks. So he’s just one of the guys that we have to take good care of.

“We have to make sure we get to the bottom of his injury and hopefully this gives his mental state of mind some peace that he can go out and rehab it and get it well for OTAs.”
