Chambers quit athletics in 2006 to pursue a career in American football

There had been reports that he was set for a dramatic return to the track after quitting the sport in 2006 to pursue a career in American football.

But organisers have confirmed that Chambers's name is not among a list of 80 entrants and never was.

The 29-year-old served a two-year ban from athletics after testing positive for anabolic steroid THG in 2003.

South of England Athletics Association administrator Linda Whitehead said: "He is not in the 60m. He has not entered.

"He can't now because the closing date was January 8."

There is a possibility that Chambers could still make a comeback at open meetings during the indoor season, where such strict entry rules do not apply.

The confirmation of his non-appearance at Pickett's Lock will please UK Athletics, which had said it was ready to stop Chambers's plans to make a competitive comeback.

It was considering a change to their selection policy so that any athlete disqualified from the Olympic Games because of drug offences, can no longer represent Great Britain at any level, such was UKA's desire to prevent Chambers from returning to the squad.

But he cannot legally be banned from running on the athletics circuit as that would be viewed as a restraint of trade.

The Londoner tested positive for THG in August 2003, after taking the drug under the guidance of his coach Remi Korchemny and nutritional expert Victor Conte.

Conte later served four months in jail for supplying athletes such as Marion Jones and Tim Montgomery with steroids through his company Balco.

Chambers was handed a ban, stripped of his medals and had all his performances since 1 January 2002 annulled.

After completing his ban, he made his return to major competition in June 2006, finishing seventh in the individual 100m at the European Championships and winning 4x100m relay gold.

But he then signalled his "retirement" from athletics by joining American football team, the Hamburg Sea Devils, only for the European league to be wound up by the NFL.

Chambers caused controversy last summer by claiming there will always be athletes using performance-enhancing drugs because the scientists will remain one step ahead of the testers.
