Tests on the sprained knee of Sean Taylor have come in negative and the rookie safety is day-to-day. It is uncertain whether Taylor will be able to participate in the first day of training camp, scheduled for Saturday, July 31.

Taylor sprained his right knee during the last 15 minutes of practice on Wednesday. Head coach Joe Gibbs said Taylor sustained the injury while defending a pass play on the team's Astroturf field. Taylor rolled out of bounds, Gibbs said.

Strong safety Dennard Wilson, an undrafted rookie out of Maryland, had surgery on his lett ankle on Wednesday evening. On Thursday, he was back at Redskins Park wearing a cast and in crutches.

Wilson signed with the Redskins in late April immediately following the NFL Draft. The 5-10, 189-pounder started 12 games for the Maryland Terrapins last year, recording 45 tackles. He was an All-ACC honorable mention pick in his senior season.

Asked of Wilson's progress prior to the injury, Gibbs said: "He'd been doing very well. We have been impressed with him."

While Taylor's injury was not as serious, coaches and teammates hope the Redskins' first-round draft pick (fifth overall) does not miss extended time on the practice field this preseason.

"It's real important for him to get those reps and get out there with his teammates," cornerback Fred Smoot said. "He needs to learn what his teammates like to do and where he fits in with the scheme. So it's very important that he get those reps and play in the preseason."

Players have Thursday off before reporting to the National Conference Center in Leesburg, Va., on Friday for a team meeting. The team will hold two practices on Saturday, the official start of Redskins Training Camp Built by The Home Depot. One practice starts at 9 a.m. and the second starts at 4:30 p.m.
