The Dallas Cowboys have become the first NFL team to offer voluntary AIDS testing, and club president Tex Schramm said yesterday that all the players who took the tests passed.

"Fortunately, everybody was negative," Schramm said. "It helps to know that we have an AIDS-free club. There has been a lot of concern that AIDS blood can be transmitted from a carrier to someone who has an abrasion. There are a lot of cuts and scratches in football."

Meanwhile, Houston Oilers Coach Jerry Glanville said his team was offering a screening test on a voluntary and confidential basis.

Glanville said a doctor was brought in during Houston's mini-camp several weeks ago to lecture on the dangers of AIDS. He estimated about 80 players attended.

"We made a deal with the football team that anyone could be tested that wanted to be tested. I don't want to know who is tested," Glanville said.

Cowboys players thought voluntary testing was a good idea.

"It's a great idea because we all live together six months out of the year," Cowboys quarterback Danny White said. "I'm surprised other teams haven't done something like AIDS testing. I think it's critical. We even use the same razor blades."

Running back Tony Dorsett said: "I think it's a good thing on a volunteer basis. It's free, too. They tell me an AIDS test is very expensive. I'm glad the club decided to do this type of thing.

"The only question I have is would they pay a player's salary for the year if it was determined he had AIDS. Would they release him?"

Schramm said that if any player had tested positive, "that would be a private thing between him and his doctor. Of course the club would want to help the individual."

The Cowboys are preparing an educational program about AIDS to be conducted by counseling services director Larry Wansley.

The Cowboys' doctors and trainers are wearing rubber gloves to deal with blood-related injuries. "There were three recent cases where health care service workers have contracted the disease through bleeding," Wansley said. "We are learning a lot of new things about the disease that we never knew before."

Dallas front office personnel also volunteered to take the test.

Saints:Starting quarterback Dave Wilson signed a three-year contract.

Wilson, going into his sixth season, would not disclose the terms, but he made a general comparison to the $450,000 that Bobby Hebert is reported to be making.

"He signed a great contract. I signed a good one," Wilson said.

Hebert started the first three games last year, then broke a foot in the third game. He returned for the final seven games, but Wilson continued starting.

Wilson said he has recovered from a shoulder strain he suffered during weight training last spring.

Lions: Owner William Clay Ford says General Manager Russ Thomas is scheduled to retire in two years, but Thomas says that's news to him, according to a published report.

"We've never discussed it. I've never thought about it," Thomas told the Detroit News.

Ford said Thomas, who has been with the team for 41 years, would retire soon after his 65th birthday in July 1989. Thomas has been a frequent target of blame for the team's misfortunes over the years.

Browns: Kicker Matt Bahr was placed on the physically unable-to-perform list, and he will likely miss at least the first three preseason games. Bahr, 31, still is rehabilitating the knee he injured Nov. 23 on a kickoff against the Pittsburgh Steelers. He was having his best season. In the offseason, Cleveland released former Redskins kicker Mark Moseley, who replaced Bahr late last season.

Chargers: Two draft choices agreed to contracts, leaving only first-round pick Rod Bernstine unsigned. Third-round draft choice Karl Wilson, a defensive end from Louisiana State, and defensive back Anthony Anderson, a 10th-round pick from Grambling, were at practice yesterday.
