Offensive tackle Mike Williams sat out Tuesday afternoon's practice after suffering a sprained ankle during the morning session.

It's uncertain if Williams will miss any additional practice time.

Williams has been one of the feel-good stories of training camp after he lost more than 100 pounds to get in shape and make a run at a Redskins roster spot.

A former 2002 first-round draft pick, Williams has not played in an NFL regular season game since 2005.

Williams was at 342 pounds at the start of camp and has continued to lose weight in the heat of training camp. A recent report had him listed at 337 pounds.

Williams' body has had to catch up, so to speak, to his weight loss. He has had to adjust his footwork and technique to his new body frame, coaches say.

It has not always been an easy transition.

Midway through training camp, Williams was slowed by an abdominal injury. He was healthy enough to play in last Thursday's preseason game at Baltimore.

Williams is competing with Stephon Heyer and Jeremy Bridges for the Redskins' starting job at right tackle.

-- ORAKPO GETS TAPED

Rookies are going to be looking over their shoulder now.

Top draft pick Brian Orakpo was taped to a goalpost following Tuesday afternoon's practice, along with undrafted rookie J.D. Skolnitsky. They were also dunked with a bucket of water.

On Monday, Kevin Barnes and Robert Henson received the same treatment.

After 15 minutes, Orakpo and Skolnitsky started to shake themselves loose. Then Andre Carter started to make his way to the field to cut them loose. He would not be pleased if they escaped on their own.

"Tie yourselves back up!"

So they did.

After freeing the two rookies, Carter said: "They handled it well. They took it like champs.

It appears Albert Haynesworth and Cornelius Griffin are the instigators, but they get plenty of help from London Fletcher, DeAngelo Hall and Fred Smoot, among others.
