Redskins quarterback Robert Griffin III was a full participant in Wednesday’s practice, though he said he expects to continue to wear a brace on his wobbly right knee for the foreseeable future – which includes Sunday’s playoff game against Seattle.

Griffin said his sprained lateral collateral ligament, suffered Dec. 9 against Baltimore, feels “better every day, every week.” He believes he now may be hindered more by the brace than by the injury itself.

“It’s getting pretty close to just being mostly the brace,” Griffin said. “But the doctors aren’t going to let me take it off, I don’t believe, and [head athletic trainer Larry Hess] is not going to let me take it off. So I try to do as much as I can without the brace, and then whenever they find out that I don’t have it on, then I have to throw it on.”

Griffin completed just 9 of 18 passes for 100 yards and no touchdowns – a passer rating of 66.9, his lowest of the season – in last Sunday’s victory over Dallas, which clinched the NFC East championship. But even with what appeared to be something of a limp, he ran six times for 63 yards.

“I know a lot of people talk about the limp with the brace, but any time you wear a brace like that, it’s to protect you, so it’s gonna cause a natural limp,” Griffin said. “You’re not going to be able to bend your knee normally. It restricts your flexion and your extension, so it’s just to protect the ligaments in there, so there’ll be a natural limp in there, but at the same time you can still generate power.”

Redskins Coach Mike Shanahan said he didn’t believe the injury is affecting Griffin’s accuracy, even though his 50 percent completion rate against Dallas was his second-lowest of the year.

“He’s wearing it so we can protect it,” Shanahan said. “Probably doesn’t have to wear it, but the doctors thought it would be best for him to wear it, to protect it, so we don’t further injure the LCL. Like I said last week, he still can run. He still can run well.”
