Robert Griffin III injured with knee sprain, no significant ligament damage

Washington Redskins rookie quarterback Robert Griffin III has a right knee sprain, the team announced Sunday night, but he escaped serious ligament damage.

Griffin, the sensational rookie quarterback, suffered the cringeworthy injury late in the Redskins' come-from-behind, overtime victory over the Baltimore Ravens on Sunday. Both Griffin and the team had feared more serious ligament damage, but the Redskins said the MRI came back "clear."

Griffin's status for next week is still unknown, however. The Redskins sit one game back of a playoff spot in multiple scenarios heading into next week's crucial game at Cleveland.

Griffin thanked his fans via Twitter for their "positive vibes and prayers."
