Danilo Di Luca and the International Cycling Union (UCI) have denied claims made on Monday that the Italian is being investigated under the UCI's biological passport program.
Spanish sports daily AS reported that the UCI was investigating results of doping tests undertaken by Di Luca at May's Giro d'Italia that did not match data complied as part of the rider's biological passport.
Di Luca, a winner of two stages and second overall at this year's Giro, said he was unaware of any investigation taking place. The Italian told Cyclingnews that he had been in contact with the UCI over the matter and that they had confirmed to him that there were no problems with his test results from the Giro.
President of the UCI, Pat McQuaid, denied on Monday afternoon that the sports governing body, as far as he was aware, was placing Di Luca under any scrutiny.
Di Luca has instructed his lawyers to contact AS in relation to their allegations.
