Robert Griffin III put on his knee brace and passed the perfunctory Redskins conditioning test on the eve of training camp in Richmond, Va., then declared he has ‘‘nothing left to prove’’ — at least physically — in his return from major knee surgery.
That’s doesn’t mean he’s all the way back.
Griffin said Wednesday he won’t participate in 11-on-11 drills in the early days of camp and likely won’t play in any preseason games. The quarterback who likes to keep the throttle wide open is going to have to exercise a bit more patience as he and coach Mike Shanahan — who have shared blame for how Griffin got hurt — try to work together to get him on the field for the regular season opener Sept. 9.
