Trailing 28-20 to Baltimore late in the fourth quarter, Robert Griffin III took off on a run and suffered what appeared to be a nasty leg injury when he bumped into Ravens defensive lineman Haloti Ngata.

After heading off the field, Griffin returned soon after in an attempt for Washington to make one last gasp to tie the game.

Noticeably limping and with the pain too much to bear, RG3 left again after a couple of passes; giving way to backup quarterback Kirk Cousins.

Washington’s other rookie quarterback managed to help the Redskins tie the game and eventually win it in overtime, 31-28.

However, the win’s excitement faded quickly in post-game over Griffin’s injury. The former Baylor Bear addressed the media and said he didn’t believe it was an ACL injury or that anything was broken.

However, Griffin will undergo an MRI tonight, according to NFL Network’s Albert Breer.

Washington is one back in the loss column in the NFC East as they try to surpass the Giants atop the division.
