Jamaica's anti-doping program was audited after a former Jamaica director alleged it didn't drug-test its athletes for months before they dazzled at the London Games. The ex-director, Renee Anne Shirley, indicated a near-complete breakdown in the agency's out-of-competition testing from January 2012 until the Olympics in August.
"They have found and suspended some athletes which is positive and a good move," Diack said. "We must stop all these. We are doing our best in athletics. You rarely hear of four-year suspensions in football but they have doping concerns too."
Bolt said he lost a potential sponsorship deal because of the doping controversy surrounding Jamaica. He did not name the sponsor but claimed that it decided against an endorsement deal after reading media reports that the country could be ineligible for the 2016 Olympics in Rio.
"It is a problem because a sponsor came up to me and an agency advised them that they should not work with me," Bolt said. "There is a lot of things going on with this drug thing that I feel needs to be corrected and clarified because it is causing a lot of problems for me and my sport. We need to get everything sorted up because for me it's really costing me money now and I am not too happy about it."
