The clearing of Iban Mayo of a doping offence by the Spanish cycling federation has been called into question by the sport's world governing body UCI who claimed on Tuesday the case was not over.
The Spanish cycling federation on Monday cleared Spanish cyclist Iban Mayo, who tested positive for blood-booster EPO during the 2007 Tour de France, after a second test proved negative, his lawyer and the federation said.
However the UCI said on Tuesday: "The second sample is not negative. The analysis of it has not yet finished."
Mayo, a specialist climber, tested positive for blood-booster EPO during the Tour on July 24 and a test on his B sample was carried out in August.
He would have been suspended for a minimum of two years if his B sample had proved positive.
