The Washington Redskins and the agent for top draft choice Brian Davis have made little progress in contract negotiations, both sides said yesterday, leaving the possibility that the rookie cornerback will not report to training camp Sunday.

"I'd say our progress has been slow to nonexistent," said Art Wilkinson, Davis' Philadelphia-based agent. "I exchanged {contract} numbers with Bobby {Beathard, general manager}, and then he went on vacation . . . We have not really done anything."

Beathard, back from vacation yesterday, said the two sides are not "arguing, but we're not making any headway, either . . . I can say that we're not close."

In another development, the Redskins, who open training camp Sunday and begin practice Monday at Dickinson College in Carlisle, Pa., apparently have decided to release kick returner Ken Jenkins.

"I'm probably not going to go to training camp," said Jenkins, a four-year veteran who now works as a sports reporter for WJLA-TV-7. It is believed the Redskins are planning to use Eric Yarber and Dwight Garner as kick returners this season, as they did when Jenkins was injured at the end of the 1986 season.

The Redskins are one of seven NFL teams that have not signed any draft choices. Washington has 11. The Redskins also have 14 veteran free agents, including quarterback Jay Schroeder, offensive linemen Joe Jacoby and Jeff Bostic, defensive tackle Dave Butz and linebackers Mel Kaufman and Rich Milot.

Beathard said running back and special teams player Reggie Branch, one of the unsigned players, reached an agreement with the Redskins. "We're close on most of the others," Beathard said.

A player cannot practice at training camp without a contract. Rookies and selected veterans, including quarterbacks, are due to report Sunday, other veterans Aug. 1.

Schroeder appears very close to signing a new three-year deal believed to be worth $900,000 to $1 million per year, which would make him the team's highest-paid player. Last year, Schroeder made a reported $225,000 in the last year of a three-year contract signed when he was a rookie in 1984. Beathard said he expects Schroeder to be signed before his first scheduled practice.

If Davis, the 30th player drafted overall, does not sign in time, he would become the Redskins' fourth consecutive top draft choice to miss part of training camp in a contract dispute. Defensive linemen Bob Slater (1984) and Markus Koch (1986) missed part of their first week of practice, and cornerback Tory Nixon (1985) missed two weeks and later was traded to San Francisco.

It is believed Davis and Wilkinson are seeking a package deal that will average about $250,000 per year.

Tackle Wally Kleine, Washington's other second-round selection, also is unsigned. His agent Bob Woolf could not be reached for comment.
