Although they are supposed to report to training camp by 6 p.m. Saturday, it's likely none of the Washington Redskins' unsigned veterans -- running back John Riggins, kicker Mark Moseley and defensive tackle Dave Butz -- will arrive on time.

Riggins and owner Jack Kent Cooke still have not reached an agreement on a contract, Cooke said today by telephone from his Elmendorf Farm, Inc., in Lexington, Ky.

They last spoke Wednesday at Cooke's Middleburg, Va., estate.

Riggins is asking for a one-year deal believed to be worth more than $1 million, according to sources. It is considered likely he and Cooke will talk sometime this weekend, perhaps Saturday.

Riggins was the highest paid Redskin the previous two seasons. His two-year guaranteed contract, which included substantial annuities and deferred payments, totaled $1.6 million for 1983 and 1984.

Riggins could not be reached for comment on the negotiations. Cooke declined to discuss specifics.

Meanwhile, it was reported negotiations with Moseley are close to being completed. Although there appears to be some disagreement over guaranteed payments, including a signing bonus, the Redskins are said to have offered him a three-year, $730,000 contract, not including incentives and bonuses.

Apparently, this deal would make Moseley, 37, the highest paid kicker in the National Football League, at least in terms of base salary.

General Manager Bobby Beathard said he expected to hear from Moseley's attorneys late tonight. All indications were that the deal will be completed soon and Moseley will report Sunday.

It has not been expected he would want to miss much of camp because of his impending battle with Tony Zendejas, the former U.S. Football League kicker who recently received a $100,000 signing bonus from the Redskins. Their competition likely will be the most intense in training camp.

Butz, who apparently still has no firm contract offer from the Redskins, will not arrive until Monday night, Beathard said today.

Butz is expected to fly in for a Tuesday meeting with Cooke at the team's Dickinson College training site. If he agrees to a contract, he will stay and begin practicing, Beathard said.

If not, he will return home.

Butz made $230,000 last season, plus about $35,000 in incentives. He has received a qualifying offer of $250,000, the standard 10 percent increase over his old contract.

It is expected he will receive a two-year contract.

This will be Butz's third trip from his home in Belleville, Ill., to negotiate with Cooke in the past five months.

Four veterans are on the 54-player traveling squad for Saturday's scrimmage against the New England Patriots: quarterbacks Jay Schroeder and Babe Laufenberg, wide receiver Ricky Smith and defensive tackle Paul Sverchek. Several players will not participate because of injuries: offensive tackle Mike McClearn (finger), center Chris Osswald (ankle), safety Kurt Kafentzis (finger), defensive end Willie Roseborough (knee), tight end Keith Smith (ankle), defensive tackle Dean Hamel (triceps) and cornerback Greg Rogers (thigh) . . . There was no progress in negotiations with holdout rookie cornerback Tory Nixon, Beathard said. Nixon has missed eight days of training camp . . . Special teams coach Wayne Sevier, who may be suffering from a hiatal hernia, will undergo more tests here Sunday, he said.

The Redskins placed five rookies on waivers today to reduce their roster to 107 players. The five were safety Napoleon DuBois, running back Roger Suelter, linebacker Alvis Satele and wide receivers Andre Gray and Kirk Pendleton.
