ASHBURN, Va. -- Albert Haynesworth was sidelined after a just few snaps at Washington Redskins practice Tuesday morning, apparently because he wasn't feeling well.
The two-time Pro Bowl defensive tackle began the workout as usual, participating in defensive drills, but he was out of his pads and standing on the sideline with a towel on his neck shortly after the 11-on-11 plays began.
Haynesworth remained with his teammates until the end of practice and referred questions to coach Mike Shanahan.
"I just think he wasn't feeling good," Shanahan said. "The doctors didn't feel like it was heat-related. He just was sick."
Haynesworth missed the first nine days of training-camp practices because he had to pass a conditioning test. He since has been mostly working with the second-string defensive line.
Linebacker Curtis Gatewood, who experienced heat exhaustion Monday, also didn't practice. Wide receivers Malcolm Kelly (hamstring) and Mike Furrey (concussion) remain sidelined. Veteran defensive players London Fletcher and Vonnie Holliday were given the day off.
The practice was a sloppy one, with players on both sides of the ball losing focus as the team worked on varying snap counts at the line of scrimmage. At one point, Shanahan called the entire team together and gave them a quick lecture on concentration.
"What you do, if you're making a few mistakes, you stop practice and you emphasize the point you're trying to get across," Shanahan said. "I did that a couple of times today. This is usually the week where everybody's a little bit sore and everybody's looking for camp to get over with."
