Limping: LT Trent Williams tried to practice with a bruised left foot, but his day ended a bit earlier than hoped. He had planned to only take about half the reps in full-team work, but he was forced to quit early because of soreness. Williams was clearly limping at the end of some plays and lacked his usual quickness.

Hurting Helu: RB Roy Helu missed another day of practice because of Achilles tendinitis in his left foot. Helu said he suffered from a similar issue last season, but that it wasn’t to “this extreme.” The Redskins aren’t sure when he’ll return. Helu’s durability was a big question mark entering camp; it remains so.

RG3 Update: Quarterback Robert Griffin III had one of his better days throwing the ball. He wasn’t under as much intense pressure, which helped. He was able to calmly deliver better throws, including a beautiful toss to Pierre Garcon in the soft spot of a cover-2 look. The pass was down the left sideline, between sinking CB Josh Wilson and S Madieu Williams, racing over. Griffin was more accurate than he had been much of camp.

Second-year jump: LB Ryan Kerrigan, who played every snap as a rookie in 2011, has looked sharp this summer. Or the Redskins’ linemen he’s working against aren’t very good, which is possible. Still, Kerrigan has improved by staying a little lower as he reaches the blocker. It’s enabled him to drive them back, especially vs. the run, and force backs to cut inside sooner. Kerrigan routinely beats his man in camp, whether it’s a tight end or the right tackle.
