Dwain Chambers will compete against world record holder Usain Bolt over 100 metres at this month's Golden Spike event in Ostrava.
Chambers, who is now eligible for selection for the London 2012 Olympics after the British Olympic Association's lifetime ban for drugs cheats was ruled non-compliant, had been invited to the May 25 event prior to that verdict being reached by the Court of Arbitration for Sport (CAS) earlier this week.
Alfons Juck, the meeting manager for Golden Spike, said: "I can confirm that Dwain Chambers has been invited to the Golden Spike event.
"At the start of the year his agent and lawyer approached all the meetings, including Ostrava. We just waited for the announcement, I wanted to see how it would end with the CAS situation, with the BOA and so on and then we published it.
"But it had nothing to do with the decision over whether Dwain would run in Ostrava or not. We just waited because we thought from a PR point of view it would be more wise to wait, then put it into the right perspective."
Chambers served a two-year ban after testing positive for a banned steroid in 2003.
In addition to Chambers and Bolt, the meeting currently will feature three other men who have gone under 10 seconds - American Darvis Patton, Jamaican Lerone Clarke and Zimbabwe's Ngonidzashe Makusha.
Britain's Harry Aikines-Aryeetey has also been invited to compete in the race.
Siza Agha, Chambers' legal representative, explained the background to the invitation and hinted at more opportunities to come for the sprinter in the run-up to the London Games.
"Alfons invited Dwain to a meeting at Dubnica in September and he did that because he felt Dwain deserved that opportunity," he said.
"We at the time discussed the possibility of Ostrava (in 2012) and Alfons said he would monitor that, and now he has been invited.
"It's a case now of seeing how things develop over the next two or three weeks. There are a lot of discussions going on, with a number of people, not just inside the sport but also outside the sport and it's important to let those discussions take their full course and then we can assess it.
"It's all very positive, and it's no less than Dwain deserves."
what do you think?
Chamerbs to Face Bolt's backside, because that's all he will be able to see
good luck to dwain, hope he makes it to the olympics. he proves that you can see the error of your ways and turn your life around.
Once a cheat, always.... ban him! He took drugs and was proved to have taken them, has admitted it and is now telling the authorities how he did it! Should never be allowed to compete again. I applaud the BOA for condenming him and trying to uphold his ban. I want to see the best athletes trying to catch Usain Bolt, not some athlete on amphetamines!
