CARLISLE, PA., AUG. 26 -- The Washington Redskins broke training camp tonight, leaving Dickinson College with almost as many questions as they arrived with 32 days ago.

Injuries have created havoc at some key positions. Knee injuries suffered by defensive end Dexter Manley and middle linebacker Neal Olkewicz have altered the look of the Redskins' defense, while other injuries have made things confusing at running back and tight end.

Running backs George Rogers (sprained left big toe) and Kelvin Bryant (strained right quadriceps) practiced today, but their availability for Saturday's third preseason game, at Tampa Bay, is in doubt.

Coach Joe Gibbs said H-back Terry Orr's bruised left shoulder, which has not healed well, has "complicated" the picture at tight end.

"I think those {backup} spots are kind of up for grabs," Gibbs said. "We're just going to play all those guys on special teams. I want to see who's the best special-teams player. We'll try to do the same thing at receiver. Any spot where we've got questions, we'll try to load the guys up on special teams and evaluate who's the best at those spots."

Gibbs is more certain about other areas of his team with the regular season just 2 1/2 weeks away.

"I think our offensive line is going to be deep," he said in a training camp summary. "I think the same thing with our secondary. I think our injuries hurt us some at linebacker, but we'll just have to wait and see how we come out there."

The Redskins today released wide receiver Laron Brown, their 11th-round draft choice from Texas, and free agent wide receiver Carl Williams of Louisville.

Rookie tackle Ed Simmons suffered a bruised left knee in tonight's scrimmage, but "it's nothing serious," Gibbs said. Rookie cornerback Johnny Thomas sprained his left ankle.
