Washington Redskins defensive tackle Dan Wilkinson sprained his left ankle during this afternoon's practice and limped off the field after the injury was wrapped and treated.

Wilkinson went down when defensive end Kenard Lang, who plays alongside him, tried to shed a block from tight end Stephen Alexander and, in doing so, threw down Alexander on Wilkinson's leg during a nine-on-seven drill.

"I don't think it's severe," Wilkinson said, "but it's sprained pretty good."

Trainer Bubba Tyer called it a mild sprain and said he would evaluate Wilkinson's status on a day-to-day basis.

Wilkinson came on strong late last season, picking up his game after fellow tackle Dana Stubblefield underwent arthroscopic surgery on his knee following the Redskins' 0-7 start. Wilkinson finished the year as the team's leader in sacks (7 1/2) and quarterback hurries (50).

Russell Out

Linebacker Twan Russell will not practice Tuesday after suffering a mild concussion when he rammed helmets with fullback Larry Bowie in practice. Russell never lost consciousness, but became dizzy after walking away from the collision. He was wincing in pain as he was driven off the field in a golf cart to be examined by a doctor. A CAT scan was scheduled later in the evening as a precaution.

"The doctor said neurologically he looked fine," Tyer said, "but we'll just keep an eye on him."

Tyer said he expected Russell, who is challenging Shawn Barber for a starting spot at outside linebacker, to be able to return by Wednesday.

Lions Miffed

According to league sources, Detroit Lions officials are angry at the Redskins over the reports detailing Washington's interest in trying to trade for now-retired Lions running back Barry Sanders. One league official said today, however, that it would be difficult for the NFL to penalize the Redskins under its tampering rules because no Redskins official ever has said publicly that the team is interested in trading for Sanders. The official called the Redskins' behavior in the matter "troubling," but said he was unaware of any formal charges.

Redskins owner Daniel M. Snyder has been reprimanded once under the league's tampering rules, after saying he would be interested in Deion Sanders if the Dallas Cowboys cornerback were to be available. Sanders never became available.

Ticket Takers

Redskins officials said they sold about 1,000 of the 2,000 remaining club seats at Jack Kent Cooke Stadium during Saturday's open house there.

The so-called "Tag Day" was designed to give fans a chance to sample the available club seats firsthand. Fans were invited to sit in the roomier club seats and tour the lounge, restaurant and sports bar that are available to club seat ticket holders. The available seats were identified with paper tags. A second tag day has been scheduled for Aug. 28, if seats remain. The open house was the first major marketing initiative undertaken by Dan Cohen, recently appointed by Snyder as the team's vice president of sales and ticket operations. . . .

The Redskins released punter Travis Colquitt in order to sign safety Marcus Stanton, who had been with the team briefly during training camp last year. Coach Norv Turner said he hoped to re-sign Colquitt later, after the competition at other spots has shaken out.
