RG3 participates in full-team drills Sunday

It looks as though Washington Redskins quarterback Robert Griffin III will be good to go for the team's third preseason game.

Griffin participated in 11-on-11 drills during Sunday's practice, just 72 hours after a concussion forced him out of the Redskins' 21-17 victory over the Detroit Lions.

Head coach Jay Gruden said Thursday that he was unsure how long Griffin would be sidelined, but Mike Jones of the Washington Post later reported that the concussion was not believed to be severe.

Washington's next preseason game is Saturday against the Baltimore Ravens.
