Dwain Chambers misses deadline to appeal Games ban

British sprinter Dwain Chambers has missed the deadline to lodge an appeal against his ban from the Beijing Olympics for serving a two-year doping suspension, the British Olympic Association said.

An association spokeswoman said athletes had been given until February 15 to appeal against any ban to ensure it was processed in time for the Games opening on August 8.

"The deadline was Feb. 15 if he (Chambers) wanted to compete in Beijing," she said. "We haven't received any communication from him as far as I am aware."

The spokeswoman said Chambers could still appeal any time against the lifetime ban imposed by the BOA on any athlete testing positive for drugs.

Chambers, 29, was banned for two years after testing positive for the designer steroid THG in 2003.
