RICHMOND, Va. – Quarterback Robert Griffin III put on his knee brace and passed the perfunctory Washington Redskins’ conditioning test on the eve of training camp, 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. Griffin is going to have to exercise a bit more patience as he and Coach Mike Shanahan try to work together to get him on the field for the regular-season opener Sept. 9.

“They want to make sure we’re not doing anything too soon that we don’t have to do,” Griffin said. “Let some of these other guys get ready for the preseason. If it comes around that I’m ready to go, then maybe in the third preseason game, but as far as my understanding goes, preseason’s really not even in the air. I think Coach feels like I can play without any preseason, so there’s no need really for that. Patience is the key.”

Griffin had reconstructive surgery on two ligaments in January after injuring his right knee multiple times in a playoff loss to Seattle. Team doctors and coaches cleared him for practice within the last week, setting a remarkable pace for a rehab that can typically take a year or more.

COWBOYS: Receiver Dez Bryant is the star of training camp, playing like a leader after his first trouble-free offseason in three years.

“I’m just impressed at this stage with how he’s handled himself,” said the owner, Jerry Jones. “Those that are the closest to him, those that have a dog in the fight, so to speak, which our fans do — a lot of other people are rooting for Dez, too — it’s a consensus that he’s making great strides.”

Coming off career bests of 1,382 yards, 12 touchdowns and three games played with a broken finger, Bryant is diving for balls more than six weeks before the regular-season starts.

“Truth be told, I love this game so much,” Bryant said. “Even if we weren’t getting paid, I’d still be probably be out and be a football player. That’s what I love to do. You’ve got to have a strong passion to be great.”
