Further blow for Chambers

Euromeetings' spring assembly in Valencia, with around half of the 51 meeting promoters present, unanimously agreed to exclude drug cheats who could cause negative publicity from participating .

However, they backed off from imposing the decision as a cartel, believing if they do it on an individual basis there will be less threat of legal action.

"We discussed mainly the athletes coming back from two or more years ban and since 2003," said Euromeetings president Rajne Soderberg.

Effectively that could mean a total blackout imposed on Chambers, who tested positive for tetrahydrogestrinone (THG) five years ago and served the mandatory two-year punishment.

Chambers may feel some meetings will jump ship and offer him invitations - as has happened in the past, notably with Marion Jones a few years ago.

But with the sport's reputation constantly spotlighted for the wrong reasons, it will be surprising if it happens in the future.

Indeed, the big meetings in London, Stockholm and Zurich will no longer invite any offender who has served a two-year ban or longer.

The Bislett Games in Oslo already does so, believing it has the right to decide who competes there, and there has never been a challenge to its decision.

It will be a further blow to Chambers, who is hoping to resume his comeback after the success of winning the World Indoor 60 metres silver medal on Friday.
