John Riggins, who still has not agreed to a contract with the Washington Redskins, is asking for a one-year deal believed to be worth more than $1 million, according to sources.

Riggins, 35, spoke with team owner Jack Kent Cooke by telephone Wednesday but there was no agreement, Cooke said.

Riggins is required to report to the Redskins' Dickinson College training camp Saturday by 6 p.m. if he has signed. He has said he will not arrive if he has not agreed to a new contract.

"I expect that John will be in Carlisle on Saturday," Cooke said today, declining to elaborate on specifics of their negotiations.

Riggins could not be reached for comment.

Coach Joe Gibbs said after a rainy practice today that he doesn't know what to expect of these negotiations.

"I wouldn't put it past John to do almost anything," Gibbs said, smiling, "or Mr. Cooke, either. I hope they'll get it worked out. I'm hoping he's going to be here."

Riggins, who gained 1,239 yards last season despite severe back problems, 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.

The status of the Redskins' two other unsigned veterans -- kicker Mark Moseley and defensive tackle Dave Butz -- remained unclear tonight.

After meeting with General Manager Bobby Beathard for more than an hour in the team dormitory, John Kovin, Moseley's attorney, said the two sides have not reached an agreement.

Kovin and partner Jim Duff said they planned to contact Moseley late this evening to tell him what the Redskins are offering.

"It's really going to be how it strikes him," Kovin said. Moseley is asking for a three-year contract that would include some guarantees.

"We are close enough that we hope to receive Mark's favorable consideration of most of the elements of the contract."

The Redskins recently paid a $100,000 signing bonus to former U.S. Football League kicker Tony Zendejas, who is expected to give Moseley, 37, the second-oldest kicker in the National Football League, perhaps the toughest battle of his career.

Beathard and Kovin plan to speak by phone Friday afternoon to discuss Moseley's reaction to the Redskins' offer.

It is possible that Moseley could miss the first few days of camp if he does not like the offer, but it is unlikely he will hold out long, considering the presence of Zendejas in camp.

Butz, meanwhile, said by phone from his home in Belleville, Ill., that he definitely will not arrive at training camp on time Saturday.

"It's logistically impossible," he said of his 800-mile drive with his wife and children. "To be there Saturday, I would have had to leave early Wednesday morning."

Butz, who made $230,000 last season, plus about $35,000 in incentives, said he still has received no word about a new offer other than the official qualifying offer of $250,000, the standard 10 percent more than his old contract.

Butz, who, like Riggins, negotiates directly with Cooke, has been asked by Cooke to come to training camp to negotiate here Tuesday.

But Butz said he still has not decided if he will come without a firm offer over the telephone.

"I'd like to know some concrete figures before I make my third trip back to discuss my contract," he said.

Butz said he traveled to Washington March 21 and again on May 14 to discuss his contract but was not made a solid offer either time. He skipped the team's May minicamp.

"They told me they intended to do better (than the $250,000 qualifying offer), but I have not yet heard another offer," Butz said.

Cooke said today that he expected Butz to arrive in camp Saturday, unsigned.

"He will not be permitted on the field (to practice), but he will be allowed to use the exercise machines to stay in shape," Cooke said.

But the earliest Butz is expected to arrive now is Sunday, and even that is considered unlikely.

"I have a family to move," Butz said. "Nothing is really packed."

Butz and Beathard were expected to talk by phone this evening to determine Butz's plans.

Meanwhile, the agent for holdout cornerback Tory Nixon said he has spoken with Beathard about the possibility of trading Nixon.

"He mentioned it to me," Beathard said. "He hasn't asked for it. We don't want to trade him. We don't intend to trade him. We want him here."

Agent Larry Muno said Nixon, who is at home in San Diego waiting out negotiations, is wondering about a trade. "He's asking about it," Muno said. "It's total frustration on his part. He's thinking, 'If they don't like me . . . ' "

The Redskins apparently are in no hurry to continue negotiating with Muno. Talks stopped with the Redskins offering about $980,000 and Nixon asking for about $1,040,000, a figure that is apparently close to what players drafted near Nixon in the second round have been receiving from other NFL teams.

Cooke, who previously was not involved in the negotiations with Muno, entered them last weekend.
