The organiser of Berlin's Golden League event has said athletes trained by US sprinter Justin Gatlin's coach Trevor Graham would not be invited to the September meeting and urged other top European events to do the same.
Gerhard Janetzky, managing director of Berlin's Golden League event, said that US sprinter Marion Jones, who was once trained by Graham, was also 'not being considered' for the event in Berlin's Olympic Stadium.
'The nine athletes coached by Trevor Graham will not be invited,' he said.
'We cancelled negotiations with Marion Jones, who would have liked to have competed in Berlin.'
The Berlin event is the final leg of a European competitions which feature a jackpot of $1 million.
The decision excludes Gatlin, who tested positive for testosterone but denies any wrongdoing, and 200 metres Olympic champion Shawn Crawford.
Dwight Thomas of Jamaica, 100 metres winner in Berlin last year, will also not be invited because of his links to Graham, the former coach of disgraced world record holder Tim Montgomery and several other athletes who have received doping suspensions.
The International Association of Athletics Federations (IAAF) has said it would monitor Gatlin's case and if the US Anti-Doping Agency (USADA) procedure confirmed the violation Gatlin would receive a life ban.
Gatlin is joint world record holder for 100 metres with Jamaican Asafa Powell.
Janetzky added he hoped the Golden League meets would in the future be able to agree on a 'common line'.
'Unfortunately that did not work out this year,' he said.
