The North American Soccer League champion Cosmos have added another international figure to their gallery of stars - at least for the time being.

Johan Cruyff, 34, the recently retired Dutch midfielder of World Cup fame, joined the club yesterday in preparation for a three-game exhibition series that begins tonight when the Cosmos host a 21-man international all-star team at Giants Stadium.

Charity will be the big winner tonight. More than 30,000 tickets had been sold as of Monday night, with most of the proceeds going to UNI-CEF and the Spanish Red Cross. The visiting players, including Johnny Rep and Wilhelmus Rilsbergen, Cruyff's former teammates on Ajax of Holland, will receive only expense money for their appearance.

As for Cruyff, his bank account could prosper if the wealthy New Yorkers decide to sign him full-time for next season as many NASL insiders believe will be the case.

Three Cosmos, including 20-year-old striker Gary Etherington, a graduate of Mount Vernon High School, are part of the 19-member U.S. national team that will tour in September in preparation for the 1982 World Cup.

Cosmo teammates Rick Davis and Dave Brcic also will make the trip, which starts Sunday in Reykjavik with a match against Iceland.

The Washington Diplomats are not represented on the squad.

There also were no Dips to be found on the first two teams of the NASL all-star squad. Goalkeeper Bill Irwin and defender Jim Steele earned a honorable mention.

Darryl Stingley of the New England Patriots, paralyzed during an Aug. 12 exhibition game against the Oakland Raiders, will collect more than $1,000 a month for life from the National Football League if he never plays another game.

Under the collective-bargaining agreement between the players and owners, he would receive $1,000 per month for life, $50 a month for each of his two dependent children, his 1978 contract ($55,000) in full, about $30,000 for 1979, the option year of his contract, and payment of all medical bills.

Stingley also is eligible for workmen's compensation and Social Security disability benefits in Massachusetts, where he is employed, or in California, where the injury occurred, and "a lump-sum settlement figure for the loss of limbs, which, at the present time cannot be determined," said Jack Sands, Stingley's attorney.

Veteran jockey on Turcotte of Canada is recovering from a life-threatening bout of spinal meningitis that complicated the crippling injuries he suffered in a spill at Belmont Park, his wife, Gaetane, said yesterday.

Turcotte was paralyzed in the lower part of his body by the July 13 mishap.

A compromise contract that would make Los Angeles the site of the 1984 Summer Olympics will be approved by International Olympic Committee (IOC), Julian Rossevelt, a United States member of the IOC said yesterday.

The latest proposal is designed to settle the problem of financial responsibility for the Games and avoid loss of face by Los Angeles to the IOC in the six-month-long negotiations.

Gary W. Hutchinson, a 6-foot-1, 200-pound lineman for Playa del Rey High School in California, collapsed and died while doing wind sprints during a football practice yesterday. Efforts to revive him were unsuccessful and he was pronounced dead on arrival at Marina Mercy Hospital. He was 15.

Indian tennis player Anand Amritraj now owns a $25,000 yacht. The problem is he doesn't know what to do with it.

Amritraj won the boat when he teamed with Bruce Jenner to win the Robert F. Kennedy pro-celebrity tennis tournament.

"I might take it back to California where we have a place in Marina del Rey," Amritraj said. "I don't think I can ship it to my parents' home in India."
