The Houston Rockets center marked his return from injury Thursday with 11 points in just more than 12 minutes of play for the Chinese national team in an Olympics warmup against a Serbian squad.

Entering six minutes into the first quarter to huge applause from the crowd in the eastern Chinese city of Hangzhou, Yao appeared a little rusty but made a solid contribution to China's kickoff 96-72 victory in the four-team Stankovic Cup tournament.

The game was Yao's first since a stress fracture in his left foot ended his NBA season in February and threatened his star turn as part of China's team.

Former Dallas Mavericks center Wang Zhizhi led the Chinese team with 18 points, with 14 more added by Yi Jianlian, recently acquired by the New Jersey Nets.

WAMBACH OUT OF OLYMPICS: U.S. soccer star Abby Wambach had surgery Thursday to repair a broken left leg that will keep her out of the Olympics.

The team's leading scorer had a titanium rod inserted in her lower left leg during a one-hour operation performed by Dr. Damion Valletta, an orthopedic surgeon for U.S. Soccer. She can begin full weight-bearing activities on the leg in five to six weeks.

Wambach, the team's leading scorer, became tangled with Brazilian defender Andreia Rosa in the first half of the Americans' 1-0 win over Brazil on Wednesday in San Diego. Wambach's leg was put in an inflatable brace, and she was carted off the field.

Natasha Kai replaced Wambach and scored the game's only goal on a header in the 84th minute.

Lauren Cheney, who was an alternate, will replace Wambach on the 18-player roster.

U.S. NAMES MEN'S SOCCER TEAM: Freddy Adu, Jozy Altidore and Michael Bradley will lead the U.S. men's soccer team into the Beijing Olympics.

Coach Peter Nowak announced the 18-man roster Thursday. Forward Brian McBride, goalkeeper Brad Guzan and defender Michael Parkhurst, a former Wake Forest standout, are the three overage players allowed in the under-23 tournament.

Selecting the Olympic squad was tricky because the Beijing Games overlap with World Cup qualifying for the U.S. team.

CHAMBERS DECISION DUE TODAY: Sprinter Dwain Chambers will find out today if he has any chance of competing at the Beijing Olympics for Great Britain.

Chambers, who served a two-year doping ban from 2003-05, is seeking a temporary injunction against the British Olympic Association, which bans doping violators for life from the games.

After Thursday's hearing in London's High Court, Judge Colin Mackay said he would announce his ruling today.
