The International Gymnastics Federation in Lausanne, Switzerland, said Tuesday it will not appeal Hamm's punishment by the U.S. Anti-Doping Agency.

USADA announced July 3 that Hamm had been warned for a May 24 positive test for glucocorticosteroid, a cortisone-like anti-inflammatory. The drug is allowed if an athlete gets a therapeutic use exemption, but Hamm had failed to do that. The U.S. men leave for China today.

The FIG's announcement comes a day after Hamm's twin brother, Paul, withdrew from the Beijing Games, saying he won't be healthy enough to compete due to hand and shoulder injuries.

Jamaican in good form

Asafa Powell ran his fastest 100 meters of the season Tuesday and Yelena Isinbayeva broke her own record in the women's pole vault to highlight the Herculis Super Grand Prix meet in Monte Carlo, Monaco.

Powell had no help from the wind on a humid night, winning his event in 9.82 seconds - six-hundredths faster in Stockholm, Sweden, a week ago.

Isinbayeva cleared 5.04 meters, succeeding with her third and final attempt to break the mark she set in Rome earlier this month by one centimeter.

Radcliffe hopes to be ready for Olympics

LONDON (AP) - Marathon world record holder Paula Radcliffe will join the British Olympic team this weekend in a bid to recover from an injury in time to compete in the race at Beijing on Aug. 17.

The 34-year-old Radcliffe, who is trying to overcome a stress fracture in her thigh, will travel to the British training camp in Macau on Sunday.

''I'm glad Paula's flying out on Sunday,'' UK Athletics performance director Dave Collins said. ''I'm sure she will have been maintaining her professionalism in training.''

Radcliffe withdrew from the London Marathon in April because of a toe injury, before being diagnosed with the femur problem in May.

She was the marathon gold-medal favorite at the 2004 Athens Olympics but dropped out about a mile from the end because of stomach problems. A few days later, she dropped out of the 10,000 meters with eight laps remaining.

Radcliffe had her training interrupted by a toe injury in September 2007 when she finished second in a half marathon - her first race in 20 months after having a child.

She won the New York City Marathon in November - which served as her Olympic qualifying time - but the toe injury flared again. That forced her to miss the London Marathon, where in 2003 she set the world record of 2 hours, 15 minutes, 25 seconds.
