Griffin suffered a sprain of his lateral collateral ligament in his right knee during the Redskins victory last Sunday over the Baltimore Ravens. The injury forced Griffin to leave the game, and fellow rookie quarterback Kirk Cousins replaced him.
Redskins head coach Mike Shanahan told the media that Griffin was limited in practice on Thursday, as were London Fletcher and Trent Williams. Kyle Shanahan specifically addressed the quarterback's chances of playing, stating:
"I think it comes down to if he can hurt himself more and if he can protect himself."
The offensive coordinator also discussed altering the team's offense to limit Griffin's exposure, saying:
"That depends on how healthy he is. I don't think I'll know that until Sunday."
Washington will face the Cleveland Browns on the road Sunday as they attempt to keep their playoff hopes alive. They are currently one game behind the New York Giants in the NFC East, as well as one game behind the Chicago Bears for the last wild card spot.
