ASHBURN — Robert Griffin III still can't participate with the entire team. That hasn't stopped him from showing off at least a little of what he can do now: dropping back and throwing passes to other injured players.

That's what Griffin did Thursday; it's also what he's done for most of the Redskins' spring workouts. Griffin did not plant and drive the ball hard, but he was able to put more force on his right leg than in the playoff loss to Seattle, for example. At times Thursday, Griffin threw more off his front foot and more with his arm.

Griffin said he still hasn't done any explosive sprinting or cutting on his knee. He said he hopes to get to explosive sprinting sometime in the next few weeks and then add the cutting perhaps two weeks after that. For now, he's limited to mental reps during practices while Kirk Cousins works as the first-team quarterback. Griffin will hear the play call and anticipate where to go with the ball based on the coverage.

"It is hard to hold myself back, but I know why I am doing the rehab," Griffin said. "As long as I know what I am doing the rehab for, the struggle to hold back does not matter.

"I can do all the stuff on the field without any hesitations and that's the best part. It is all about the confidence, and if I work hard enough to get the confidence back, I can get back out on the field. "

Griffin isn't the only player recovering from an injury, but two were added to the list Thursday: corner Josh Wilson and receiver Pierre Garcon. Both are recovering from offseason surgeries that had not been disclosed before Thursday.

Wilson tore his labrum during the season, and in the process of checking that out, doctors discovered he had a torn pectoral muscle. He underwent surgery around two months ago, coach Mike Shanahan said.

Garcon also had surgery on his labrum and could not practice. Shanahan said he'd be surprised if Garcon is not at full speed once training camp begins July 25. In fact, Shanahan said as of now there's only one player he thinks might not be ready for camp -- though he would not say which one.

Offensive linemen Josh LeRibeus said he injured his left hamstring, which is why he was not practicing (Shanahan said LeRibeus had a groin issue). Guard Maurice Hurt sat out with a groin injury. Shanahan said both are around 90 percent.

Tight end Fred Davis (Achilles) said he hoped to be ready for the June 11 start of minicamp, but Shanahan said he'd likely wait to have him return until training camp.

Safety Brandon Meriweather (knee) said he anticipates being ready for training camp. He underwent ACL surgery midway through last season.
