Dr. James Andrews has been incredibly impressed by the recovery of Robert Griffin III.

"I've been real mum on talking too much about RG III. He wants his recovery to be fairly private, but I can tell you he's way ahead of schedule. His recovery has been unbelievable so far," Andrews.

"RG III is one those superhumans. First patient I ever had like that was Bo Jackson. And recently I, of course, had Adrian Peterson, who is also superhuman. They have an unbelievable ability to recover, where as a normal human being may not be able to recover."

Griffin tore the LCL and ACL in his right knee in the Washington Redskins' playoff loss to the Seahawks in January.
