SHANGHAI -- More than a week after Cesar Cielo was cleared of doping, his case remains the talk of the pool deck at the world swimming championships.
Jason Dunford, the Kenyan who turned his thumbs down when Cielo won the 50-meter butterfly earlier this week, explained his actions Friday.
"It wasn't a personal attack on Cielo. It was just on a system that seems to have let swimming down," Dunford, who finished seventh in that race, told The Associated Press. "You can call me a sore loser but that wasn't the point of my action. I don't mind losing to people. I'm just a bit disgruntled with the system that two months after a positive test he's competing against us."
The Court of Arbitration for Sport published Friday the reasons behind its decision to uphold a ruling by the Brazilian swimming federation, saying a Brazilian pharmacy was responsible for the Olympic champion's positive test.
Swimming governing body FINA had challenged a Brazilian federation decision to give Cielo only a warning after he tested positive for furosemide, a banned diuretic and masking agent, at a meet in Rio de Janeiro in May.
Cielo said he consumed the drug in a contaminated batch of a food supplement he regularly used.
Other recent doping cases involving furosemide have seen athletes banned for up to 14 months.
The CAS said the pharmacy acknowledged preparing a heart disease medication containing furosemide on the same day it made Cielo's prescribed caffeine capsules. The court added that Cielo's urine sample was not diluted, proving the substance wasn't used as a masking agent.
CAS said FINA accepted that Cielo did not take the drug to enhance his performance.
Fred Bousquet, Cielo's former college teammate at Auburn, was banned for two months at the end of last year by the French federation for using the banned stimulant heptaminol. He said at the time that he was careless when he purchased an ointment at a pharmacy he knew well.
"Everybody has his own situation and the cases are all different," Bousquet said Friday after failing to advance from morning heats in the 50 freestyle.
"I'm sure the CAS was fair in its decision and they studied everything. I'm sure they questioned everybody they could question and studied everything they could," Bousquet added. "I'm sure they're sleeping well at night, thinking that they took the right decision and I go with it."
Dunford is not so sure, and he brought up the case of his friend and fellow butterflier, Venezuelan Albert Subirats, who was banned for one year for failing to notify FINA's anti-doping authorities of his whereabouts three times within 18 months.
"There's something wrong with the system, because people are being treated differently," Dunford said. "Everyone is a bit disgruntled on the pool deck. A lot of swimmers are not happy that (Cielo) is here."
South African sprinter Roland Schoeman has also been critical of the way Cielo's case was handled.
Cielo relinquished his 100 free title to Australia's James Magnussen when he finished fourth Thursday, but he could be in medal contention again Saturday after qualifying second fastest behind Brazilian teammate Bruno Fratus in the 50 free.
After his 50 fly win, Cielo broke down into tears while still in the pool.
"For him to come here and compete, personally I think it's great," Bousquet said. "Still to be able to perform at the level where he is right now is amazing. It shows the talent and the real champion that he is."
