WIMBLEDON, England (AP) _ Clay court specialists Sergi Bruguera and Alberto Berasategui are withdrawing from Wimbledon because of injuries, and French Open champ Steffi Graf could be joining them on the sidelines.

Graf has had a series of problems this year, including a back injury, a calf strain and a virus. The calf injury prevented her from taking part in the Australian Open and the virus slowed her at the French Open, although she won.

Her absence from a memorial service for Fred Perry in London and the report about a problem with her right wrist prompted speculation about her Wimbledon chances. The report said Graf, a five-time Wimbledon winner and the top seed if she plays this year, has flown to Germany for treatment.

There was no state of panic at Wimbledon, however.

``We haven't heard anything to indicate that she won't be here,'' spokeswoman Sue Youngman said.

The All England Club, in announcing the withdrawals of Bruguera, the No. 8 seed, and Berasategui did not say what their injuries were.

Because the draw has already taken place, Wimbledon will request that both players undergo medical examinations to confirm the injuries before the championships start Monday.

Bruguera defeated Berasategui in the French Open final on clay last year, but both players have shown a disdain for grass. Bruguera has played at Wimbledon only once since 1990, and Berasategui has never played at the All England Club.

Thomas Enqvist, No. 19 in the world computer rankings and the highest-ranked player not seeded, will move to Bruguera's spot in the draw and play fellow Swede Anders Jarryd in the first round. Enqvist was not named a seed, leaving the No. 8 spot vacant.

Scott Draper of Australia will take Enqvist's previous spot in the draw and face Jared Palmer of the United States.

Berasategui, ranked No. 12 but not seeded by the Wimbledon committee, was drawn to play three-time champion Boris Becker in the first round. Emilio Alvarez of Spain will take Berasategui's place.
