The glowing reviews of Robert Griffin III’s recovery from knee reconstruction continue.

Roughly two weeks after team physician James Andrews described Griffin as “superhuman” in his recovery efforts, Redskins Coach Mike Shanahan added more praise for the quarterback.

Friday evening in an interview with NFL Network, Shanahan said he expects Griffin to make an unprecedented comeback from January’s surgery to repair a torn ACL, LCL and meniscus.

“He’s over at the facility, rehabbing all of the time. He’ll set a record for coming back because that’s how hard he works,” Shanahan said.

The coach echoed what has been said throughout the process, that Griffin is further along that what is normally expected at this point. He added, however, that the Redskins won’t know exactly how realistic the Week 1 return goal is until late this summer.

“He is ahead, but there is a process,” Shanahan said. “It takes time. Robert will do it the right way and we’ll find out in July exactly where he’s at. … He will not come back until he’s 100 percent.”

Griffin is expected to begin running on the field in the coming week as part of his rehabilitation program.
