The Washington Redskins' afternoon session yesterday, scheduled for 90 minutes, was markedly truncated because of a storm. But Coach Joe Gibbs kept his players on the artificial turf field for several minutes, before lightning appeared, so they could get accustomed to the nasty weather often found playing in the NFC East.

The Redskins have considered constructing a bubble at Redskins Park to avoid the inclement weather. However, Gibbs wouldn't consider a bubble. "Never," Gibbs said yesterday. "I don't like bubbles. You play outside. It's an outdoor game. I want to be in the rain because you have a lot of these adverse weather conditions. I don't think there's any other way to get used to that except to be out in it. You need to be out in the heat, rain, snow, sleet -- the whole deal."

Voice of Experience

Center Cory Raymer suffered a season-ending Achilles' injury in September 2002, and has already spoken to right tackle Jon Jansen about rehabilitation. "The biggest thing about the Achilles' is just the fact that you just can't push it," Raymer said . "He's just like everybody else and maybe a little bit worse than the normal person in that he's going to want to do a lot more than what he can. And it just takes time. It's an injury you'll be able to come back from 100 percent, stronger than before. You have to sit out, which is unfortunate, but he'll be back ready to go next year." . . .

The Redskins invited tackle Marcus Spriggs, an eight-year veteran, for a workout before the morning session, but the club didn't announce a signing. . . .

Although the Redskins announced the retirement of Pepper Rodgers, 72, last Friday, the club's vice president of football operations won't leave the organization until after the season . . .

San Diego Coach Marty Schottenheimer, the former Redskins coach who was fired by owner Daniel Snyder after the 2001 season, announced Wednesday that his son, Brian, the Chargers' quarterback coach, underwent successful surgery for thyroid cancer at the Mayo Clinic in Rochester, Minn. Marty Schottenheimer, who was dismissed in Washington after declining to cede personnel authority, said Snyder recommended the doctor who treated his son. "It was Dan who had the same experience several years ago,'' Marty Schottenheimer told the North County Times. "Dan was very reassuring to me about this, and the way it would go."

Injury Report

Shawn Springs returned to practice after sitting out Wednesday's sessionbecause of tightness in his quadriceps muscle. Chad Morton (ankle) and Cornelius Griffin (sore ankle) sat out but are expected to play against Carolina on Saturday at FedEx Field. Mike Barrow (tendinitis, left knee) and Phillip Daniels (abdominal muscle strain) aren't expected to play.

Center Cory Raymer and offensive line coach Joe Bugel seem to get a kick out of training camp.
