RICHMOND — Redskins coach Jay Gruden said that cornerback DeAngelo Hall suffered a bruise, and nothing more serious, when he landed on his back at the end of a play in one-on-one drill in the red zone Sunday morning.

Hall was matched up with wide receiver Andre Roberts, and Roberts caught a pass on a fade route. Hall tried to contest the throw, but did a somersault and landed awkwardly on his back. He rode a cart from the sideline to the locker room, where he received treatment. But Gruden downplayed the seriousness of the injury.

“He just got up a little sore. They carted him off just for the dramatic exit,” Gruden chuckled. “He could’ve walked off and made it a lot easier on me today.”

Gruden said he didn’t expect for Hall to miss significant time.

Hall moved gingerly following Washington’s walk-through Sunday afternoon. He didn’t stop when approached for an interview, but said only, “I’ll be all right. I’m good.”

Meanwhile, Washington had a number of other players sidelined for Sunday’s practice.

Safeties Ryan Clark and Phillip Thomas continue to nurse hamstring injuries. Linebacker Brian Orakpo sat with a thigh contusion.

Running back Chris Thompson has a low ankle sprain and could miss another five to six days, Gruden said. Backup inside linebacker Darryl Sharpton and running back Silas Redd both missed practice with high ankle sprains.

Wide receiver DeSean Jackson took part only in individual drills, but Gruden doesn’t expect that his ankle sprain will keep him out of full action much longer. Gruden hopes Jackson can play in the second preseason game on Monday, Aug. 18.
