The Washington Redskins wrapped up their first full day of training camp with a roughly 2-1/2 hour practice on a scorching Thursday afternoon in Ashburn.

Some observations:

-Quarterback Robert Griffin III wasn’t at his sharpest; a number of his passes fell short or sailed long, or flew behind receivers. Griffin had two really good passes; on one, he fired the ball to Santana Moss, who was tightly covered by safety Brandon Meriweather. Griffin put the ball into a tight spot as Moss cut toward the sideline, and the veteran caught the ball in stride.

The other was a laser pass down the center of the field to Pierre Garçon, but the receiver let the ball slip right through his hands for an incompletion. The best catch of the day belonged to Josh Morgan, who leaped for a one-handed grab along the sideline to save Griffin from another incompletion. Griffin wasn’t made available to reporters, but Shanahan and the receivers weren’t concerned. Shanahan remarked that on the first day of practice, with receivers and the quarterback having been apart for a while, timing issues are common.

-Tim Hightower took a limited number of carries as he works his way back from ACL surgery in November. Hightower ran with a slight hitch, but did display a burst of acceleration on one carry when he found a seam, eluded a would-be tackler and went the distance. Towards the tail end of the run, and on his way back to the huddle, Hightower appeared to limp a little more.

Afterwards, Hightower said he felt pretty good, but acknowledged that he is still healing. He drew encouragement from the fact that he is active, not on the PUP list. Shanahan said the back remains eager, and that he has to be reminded to be patient.

With Hightower limited, Evan Royster took the bulk of the first-team snaps and appeared to run hard. Roy Helu worked primarily with the second team, but occasionally with the starters. Shanahan said the competition remains wide open, however.

The first-team offense featured a lot of Garçon and Morgan on the outside, with Santana Moss working in the slot. Leonard Hankerson and Aldrick Robinson saw some time in the slot as well, while Anthony Armstrong and Brandon Banks primarily relieved Garçon and Morgan.

DeAngelo Hall had a near interception of Griffin, but couldn’t hang on. The ball appeared to hit him in the chest. Hall dropped to the ground and did a series of pushups for missing on the turnover.

London Fletcher said fellow inside linebacker Perry Riley has improved in formation recognition, and Riley looked good in pass coverage, breaking up a sideline pass from Griffin to Niles Paul.

Ryan Kerrigan got into the backfield and batted down a Griffin pass for the second-year pro’s first play of camp.

Trent Williams faced off with Brian Orakpo throughout 11-on-11 drills, and Williams did a good job of keeping his feet and staying in front of Orakpo to protect Griffin. Orakpo did get the best of Williams on one particular play, and Williams had to nearly clothes-line Orakpo to keep him from getting to his quarterback.

Eighty-seven of the 90 players on the Redskins’ roster participated. Right tackle Jammal Brown (hip), safety Tanard Jackson (calf) and running back Tristan Davis (knee) are on the PUP List.

The Redskins return to the field at 10:40 a.m. Friday for their closed walk-through, and then practice again at 3 p.m. That session is open to the public.
