Robert Griffin III returns to practice following concussion

ASHBURN, Va. (AP) Robert Griffin III returned to practice Sunday, three days after the Washington quarterback left the Redskins' exhibition game against the Detroit Lions because of a concussion.

Griffin fully participated in individual, 7 on 7 and 11 on 11 drills during the approximately 2-hour session at Redskins Park.

''He was cleared for non-contact activity today,'' coach Jay Gruden said. ''He'll be checked by a neurosurgeon later this week to determine whether he'll be cleared for (Saturday's game against the Ravens), but so far so good.

''He didn't have any headaches or anything of that nature. He did a good job of executing the offense today.''

Griffin wasn't available to the media Sunday. He was injured when Lions defensive end Corey Wootton landed on him while the quarterback tried to recover his own fumble early in the second quarter of the Redskins' 21-17 home victory Thursday night.

Griffin was sacked three times and fumbled twice in four possessions. He went 2 for 5 for 8 yards.
