The Washington Redskins say Robert Griffin III doesn't have a major knee injury.
Team spokesman Tony Wyllie said Sunday that Griffin underwent an MRI and has a sprained right knee but that "everything is clear" in terms of significant ligament damage.
Wyllie specifically ruled out a season-ending torn ACL.
Wyllie said coach Mike Shanahan will update the rookie quarterback's condition Monday.
Griffin was injured in the final minutes of regulation in the Redskins' 31-28 overtime win over the Baltimore Ravens.
