After offensive coordinator Kyle Shanahan admittedly held back Robert Griffin III last week against the Eagles, the Redskins may not know until game time Sunday night how comfortable they’ll be in testing the strained LCL in Griffin’s right knee.

But with only one more walkthrough left, they have been encouraged by what they’ve seen. Coach Mike Shanahan said Griffin, who will likely be listed officially as probable, has grown more comfortable playing with a brace on his right knee after wearing it for another full week of practice. He also confirmed Griffin’s knee has only improved.

“He looked good in practice today,” Shanahan said. “There has been no setback. I think he gets better and better and more comfortable using that brace. Like I said last week, some of the quarterback keeps and some of the scrambles, you could see that it was impressive last week for him to make some of those moves outside the pocket. But it has improved another week and there should be no setback for him.”

Typically, it takes one to four weeks to recover from an LCL sprain. Sunday will mark the three-week point, and so Griffin should be less limited against Dallas than he was last week against the Eagles. Griffin rushed only twice for a season-low four yards Sunday. He’s a good enough passer to still be an elite quarterback if he only throws from the pocket. But what separates the Redskins’ offense is Griffin’s running ability – and the threat of him running.

“We held him back some [against Philadelphia], but it was more the game plan from a schematic standpoint,” Kyle Shanahan said. “We ran him here and there, not as much. There weren’t as many pull reads and stuff, but he got a couple opportunities. I think he gets healthier each week. It’s only natural to get better. We’ll see what happens this week.”
