When Kory Lichtensteiger reports to Redskins Park for OTAs next month, the starting left guard will be as healthy as he’s been in 20 months. Lichtensteiger was unable to finish the Redskins’ playoff game against the Seahawks in January after tweaking the left ankle he had injured the previous week. Three months later, though, Lichtensteiger says the high ankle sprain he suffered in the regular season finale against the Cowboys is back to full strength and that he’ll have a clean bill of health when offseason activities begin. “I don’t even feel that anymore,” he said Saturday in Ashburn. “About a month into it, it was fine. It was never serious, it just takes a more time than a week [between games] to get ready for.” In addition to a healthy ankle, Lichtensteiger said that his surgically repaired right knee will be a “non-issue” for the first time since he suffered a devastating injury in Oct. 2011. Eight months after having the ACL and MCL repaired, his knee required a second procedure in training camp last July to remove loose particles.
