Two-time Grand Slam champion Mary Pierce of France isn't ready to hang up her racket just yet.

Despite being out with a knee injury since 2006, Pierce told sports daily L'Equipe that she would like to play again at the French Open.

"I care about Roland Garros. If I could stand in center court for one match, that would already be a big victory," she said.

Pierce, who turns 34 next month, won the French Open in 2000 and the Australian Open in 1995. She ruptured a ligament in her left knee in October 2006 in Linz, Austria, in a match against Vera Zvonareva. She hasn't competed professionally since.

"I don't feel it's the right moment [to announce my retirement]," Pierce told L'Equipe, adding that her left leg is weak but tests indicate her knee has recovered.

Defender Neven Subotic has chosen to play soccer for Serbia instead of the United States.

Subotic, who was born in Bosnia and holds an American passport, has played for the U.S. under-17 and under-20 teams. He now plays for Borussia Dortmund in the German league.

Subotic wrote to U.S. soccer officials, informing them of his decision to play for Serbia.

"We wish Neven all the best and continued success in the future," U.S. Soccer Federation president Sunil Gulati said.

Subotic had until next Dec. 10, his 21st birthday, to chose his senior national team under rules by soccer's governing body. He could have picked the United States, Bosnia or Serbia.

The Serbian soccer federation said on its Web site that Subotic, a Bosnian Serb, made the decision "to return to his roots." He is expected to debut for Serbia in a tournament in Cyprus in February.

Serbian coach Radomir Antic has said he plans to pair Subotic with Manchester United's Nemanja Vidic in the center of Serbia's defense in next year's World Cup qualifiers.

Subotic has scored five goals for Dortmund this season in the Bundesliga. He has been linked with a move to Napoli of the Italian league during the January transfer window.

Dr. Richard Steadman, a surgeon whose clinic has treated such athletes as Kobe Bryant, Bode Miller, John Elway and Greg Norman, said he had a serious blood clot in his lungs this month but expects a full recovery.

Steadman said the Vail Daily in Colorado he received emergency treatment Dec. 5 after his wife called 911. He hopes to resume seeing patients after the holidays.

Steadman specializes in knee surgery at the Steadman-Hawkins Clinic in Vail. He also has been the surgeon for the U.S. Ski Team.
