The Washington Redskins received a scare halfway through Sunday's morning training camp practice after cornerback and captain DeAngelo Hall was carted off the field with a back injury.

Head coach Jay Gruden later told reporters Hall "did a somersault" during individual drills in the red zone when covering wide receiver Andre Roberts, who was running a fade route.

"(Hall) landed on his back and bruised his back," Gruden said. "He is walking around a little bit better today – just a little bit sore."

Gruden said he doesn't imagine Hall's recovery time being very long.

Hall became one of several players who were either out of or limited in Sunday's practice, including:

- Wide receiver DeSean Jackson (ankle): Gruden expects him to return to full strength "very soon." "… He's running individual routes already, and he looks fine doing that. He's just going to continue doing individual. He's doing some extra running after practice, but full-speed cutting we're going to hold off probably another day or two, and then get him back into full-go action. Hopefully, he'll be ready by Monday night (Aug. 18 vs. the Browns)."

 - Linebacker Darryl Sharpton (high ankle sprain): "Sharpton's probably got the worst," Gruden said. "He's probably going to be the longest (out)."

 - Outside linebacker Brian Orakpo (thigh contusion): "He's going to be fine," Gruden said. "We just kept him out today to give him a break."

 - Running back Silas Redd (ankle sprain): "He will be ready hopefully tomorrow, maybe the next day," Gruden said. "We will see how he's doing."

 - Running back Chris Thompson (ankle): "He's got to figure out a way to stay healthy," Gruden said. "His is a low ankle sprain, and it probably will be another five to six days, I would think – just a matter of how quickly it heals."

 - Safety Phillip Thomas (hamstring): "You push them out there, you get out there too quick, you re-injure the hamstring and now you're in the same boat or worse," Gruden said about wanting Thomas back on the field. "So it's important for Phillip to get this thing 100 percent healthy and he's got to show us what he can do."

Seastrunk soreGruden said running back Lache Seastrunk has been practicing the past week or so with a sore foot.

The injury is more nagging than serious, however, and Seastrunk has been able to play through it with no real problems.

"It's important for these guys to play through the nagging injuries," Gruden said. "Obviously the ones that keep them out, we don't want to do a lot of damage to. Everybody's got some kind of bump or bruise right now I would imagine, and if you can play through it, it's great."

Gruden said Seastrunk – the team's sixth-round selection out of Baylor – is still a work in progress when it comes to his pass-catching and pass-protection abilities.

"He's good out of the backfield, he's got decent hands, he obviously can run the ball, he's very fast," Gruden said. "But as far as just fundamentals of running backs are concerned, he's a little bit behind the 8-ball as far as his footwork, his blitz pickups, some of his route definition – a little sloppy right now."

Gruden said Seastrunk wasn't asked to do a lot of the things he's doing right now when he was at Baylor, so he's playing catch up with running backs coach Randy Jordan.

"He's coming along at a slower pace than I would probably like him to come along, but he's working very hard at it," Gruden said. "Hopefully, you know we have three preseason games left that he'll be able to show us that he can handle some of these blitz pickups in practice and in games."

Two-minute strugglesThe Redskins on Sunday worked extensively on their two-minute offense and defense, and Gruden said he liked the tempo, but the execution by the offense was off at times.

But because the team only installed its two-minute packages four or five days ago, the first-year head coach isn't too worried.

"There's some good pass rush, our protection might be a little unsound, so to speak. It could be a poor read by the quarterback or a poor route," Gruden said. "There's a lot that goes into a two-minute offense."

Redskins quarterback Robert Griffin III said more practice reps can only mean good things for the Redskins' two-minute attack.

"It's just all about everybody knowing what to do, where to be in a matter of seconds," Griffin III said. "That's why we're doing it every day -- so that we can get those reps, get that consistency that we need from our guys and just the right calls that we need out there."

Team captainsGruden also confirmed Sunday that he's picked his team captains for the preseason.

Hall (defense), offensive tackle Trent Williams (offense) and linebacker Adam Hayward (special teams) represented the team at the pregame coin flip Thursday against the Patriots, and will continue to do so for the remainder of the preseason.

"Those are the most seasoned guys with the best performances," Gruden said. "The body of work, I think, has been proven on the field and they're natural leaders."

Gruden said he's yet to determine how he'll choose captains for the regular season.
