Although Dave Butz is expected to be able to start Saturday against the New York Giants, Coach Jack Pardee remained concerned yesterday about the Redskins' thin defensive tackle corps.

The only two healthy tackles are Paul Smith and Diron Talbert. Butz damaged thumb ligaments against San Diego and has not worked out this week. Perry Brooks still is hobbled by a sprained ankle and will not play.

"I believe Dave will be able to play Saturday, but he hasn't worked out all week and that concerns me," Pardee said. "We'd start Paul and Diron if Dave can't play, and use (end) Karl Lorch as a backup there, with Dallas Hickman taking Karl's place at end.

"I know the Giants would check us out up the middle anyway with their running game, and with our injury problems there, you can be sure of it. That's how they won their last game (against Seattle), anyway. They were able to run the ball and get a couple of long bombs on play-action fakes."

The Giants have had success in recent years running on the Redskins. But Washington's improvement against the rush has been a major reason the defense has turned in three straight solid performances.

Pardee has been unhappy with his players' practices this week and reprimanded them for their lack of concentration yesterday.

"We've gone over all we need to, but with the short week and the change in weather, the workouts haven't been the way I'd like," he said.
