Cheat Chambers given a chance to resume 100m career

He is expected to compete in an open international as a first step towards making it to the Beijing Games.

Lifeline: Chambers aims to be picked for Beijing

After failing to make the grade with rugby league club Castleford, Chambers returned to full-time training last week.

The 30-year-old Londoner is planning a High Court challenge to a lifetime suspension imposed by the British Olympic Association over his positive drugs test in a bid to achieve his ambition.

The opportunity to race in southern Germany - albeit at a low-key meeting - could be a lifeline for Chambers, who needs to get himself race fit before the British trials in Birmingham from July 11-13.

Biberach organisers, who could be using Chambers to drum up interest in the event, confirmed yesterday they expect an answer from Chambers within the next two days as to whether he will compete on June 28.

"Everybody can make a mistake once in their life," said the event director Heinz Husselman. "Give him a second chance."

Biberach is not a partner of Euromeetings, whose members were recommended in March not to invite doping offenders to their competitions who had served two-year suspensions since 2003.

In America, the conviction for perjury of athletics coach Trevor Graham has turned the spotlight on former sprint star Maurice Greene, the former world 100m record holder.

Greene, named last month in a newspaper interview by the primary witness against Graham, a Mexican drug seller called Angel Guillermo Heredia, is likely to be investigated immediately by the United States Anti-Doping Agency.

So are 11 other athletes whom Heredia claims to have supplied. Neither the names of these athletes nor Greene's came out in the Graham proceedings but apparently what was used in court was the tip of the iceberg.

Among the files are paperwork Heredia gave the USADA, including wire transfers for $10,000 (£5,000) which bear Greene's name.

Greene denied the charges but the IAAF, the sport's world body, confirmed that USADA would be investigating 'in an urgent way'. USADA has promised IAAF a complete dossier on their eventual findings.

Graham was found guilty of only one of three charges of lying, but it was revealed that the jury voted 11-1 in favour of conviction on a second charge and 10-2 in favour on a third.

The judge will rule on June 20 whether there should be a re-trial on those, and sentence Graham in September on his one conviction.

Local legal sources predicted a jail sentence of no more than six months.
