Guard Kory Lichtensteiger said Monday he “probably didn’t make the right decision” by attempting to play in the Redskins’ first-round playoff loss Sunday to the Seattle Seahawks on a sprained left ankle.

“In hindsight, I probably shouldn’t have done it,” he said. “But I felt like I could give it a go with the proper medication and everything. I had it feeling right, at least I thought. I felt good going to the right. Most of the series was things I could do. And then once we got to the goal line, I really had to… put pressure on that left ankle and it just didn’t hold up. So I knew it right away that it was time.”

Lichtensteiger left the game during the Redskins’ first offensive series. Rookie Josh LeRibeus played the rest of the game at left guard.

Lichtensteiger had his left foot in a protective boot Monday. He said he expects his recovery time will be less than a month. He said he wouldn’t have tried to play Sunday if it wasn’t a playoff game.

“That’s why I really tried to play,” he said. “I think if it was a regular season game, I would have realized that, hey, I should give it another week or two. But I really wanted to be out there and probably didn’t make the right decision.”
