Washington Redskins quarterback Robert Griffin III was limited in practice on Wednesday after suffering a sprained shoulder in Saturday's win over the Philadelphia Eagles, according to multiple reports.
The injury occurred when Griffin was sacked by Eagles defensive lineman Fletcher Cox in the fourth quarter.
"He can throw the ball, it's just a little sore," Gruden said Wednesday. "We just want to make sure he doesn't aggravate it more, give him another couple days of rest and be ready to go Friday."
Over eight games this season, Griffin has completed 69.4 percent of his passes for three touchdowns with four interceptions. The 24-year-old also missed time with an ankle injury earlier this season.
Washington (4-11) is in last place in the NFC East.
