BONNER SPRINGS, Kan. (AP) _ When Derrick Thomas, a Kansas City Chiefs linebacker, came on stage to join his friend Hank Williams Jr., it was not to do a duet with the country singer.

It was to calm a situation that was out of hand.

Williams admitted he was drinking before a concert at Sandstone Amphitheatre in suburban Kansas City on Saturday night that ended with him cursing the audience, his crew and other performers before leaving the stage.

''I walked out and put my arm around him, but I did that as a friend because he was going downhill fast,'' Thomas said. ''Sometimes, if somebody just walks out and breaks what you're doing, you have an opportunity to start over again.

''I just wanted to divert the crowd and give him the chance to regain his composure. But by then it was too late, and I don't think he really wanted to perform after that.''

Said Williams, ''The truth is I messed up, and I accept full responsibility for my actions.''

The ticket broker is refunding more than $200,000 to people who attended the concert.

WELLINGTON, New Zealand (AP) - Swimmer Toni Jeffs of is getting help from an unusual group of sponsors to get to the Olympics.

Strippers from a local nightclub have collected money to help Jeffs compete at the Barcelona Olympics - and will take off their clothes Wednesday to raise further funds.

Jeffs will compete in the women's 50 meters and 100 meters freestyle events in Barcelona.

She is sponsored by Tiffany's Cabaret, a strip club in the Wellington suburb of Newtown.

The club will donate the proceeds from a show on Wednesday night to help meet Jeff's training costs.

''Some people said they would prefer to give me the $10 and not go to the cabaret, but I've encouraged them to go,'' Jeffs said.

''It's not dirty or anything, just good clean entertainment.

''We were $1,750 short of our budget, so Brian Le Gros, who manages the cabaret, suggested a show.''

Jeffs said she never has been involved in stripping, but sees no reason why she should not accept the sponsorship.

AUSTIN (AP) - University of Texas outfielder Stephen Larkin, who suffers a heart condition, has been cleared to play again for the Longhorns.

Larkin, an 18-year-old freshman who batted .284, was forced to sit out seven games this season because he has hypertrophic cardiomyopathy.

Larkin's brother, Barry Larkin is a shortstop for the Cincinnati Reds.

His condition, a thickening of the heart that restricts blood flow, is believed to be the leading cause of sudden death among athletes.

Larkin and his family signed a waiver freeing Texas of any liability. But school officials said they wanted him to undergo extensive tests during the off-season.

The results of those tests at the National Health Institute at Bethesda, Md., apparently came out in Larkin's favor.

Dr. Mark Hutchens, Texas athletic director of medicine, said he will recommend to athletic director Deloss Dodds that Larkin be allowed to play.

Hutchens, who accompanied Larkin for 10 days of tests in June, said he will not receive the written report for three or four weeks, but that he doesn't expect any problems to surface.

''At this point, it looks encouraging that he will be able to participate next year,'' Hutchens said.

Dr. Lemeh Fananapazir at the National Health Institute said Larkin had a mild form of the condition, said Larkin's mother, Shirley Larkin.

ASPEN, Colo. (AP) - A sports memorabilia shop will receive a $137,500 insurance settlement to compensate it for the theft of a rare Honus Wagner baseball card.

''We got back our costs, but much less than fair market value,'' said Mark Friedland, owner of the Super Stars store.

Friedland and two other investors paid about $137,000 for the card in 1991. But in the high-stakes market of trading cards, it's worth an estimated $200,000 to $250,000.

The card was stolen the night of Feb. 28 from an unlocked display case.

The Wagner card, released about 1909, is valuable because only about 40 of them have ever surfaced. Wagner, a Pittsburgh Pirates' shortstop, demanded that Sweet Caporal Cigarettes stop distributing the cards because he opposed smoking.

Friedland said he wanted to offer a reward for the card, but his insurance company was against the idea. Now, even if the card is found, the insurance company will have the rights to it, he said.

LONDON (AP) - British decathlete Daley Thompson will attempt to qualify for his fifth Olympic games through a meet in Norway Saturday.

British track selectors broke their own rules Monday to give the two-time Olympic gold medallist and world-record holder a last chance to meet the qualifying standard of 7,850 points after he missed the British trials through injury.

Thompson and teammate Alex Kruger have entered the two-day event at Trondheim, Norway. Thompson pulled out of German competition last week with a shoulder injury, but insists he is capable of completing his first decathlon in four years.

Thompson, 33, set the current world record of 8,847 points to win the Olympic gold at Los Angeles in 1984, after winning the event four years previously in Moscow.
