Having been accused of doping after abnormalities in his biological passport were discovered, Czech cyclists Roman Kreuziger has slammed anti-doping bodies over delays in his case that has hampered his career.

“I never cease to be amazed. Another delay,” the 28-year-old Tinkoff-Saxo rider wrote on Twitter, blaming the Court of Arbitration for Sport alongside the international cycling association UCI and the WADA anti-doping watchdog.

The CAS has proposed June 10 “for the hearing and (the) verdict a month later. UCI/WADA rejected 2 proposed dates!” Kreuziger said.

The hearing was originally scheduled for the turn of March and April.

“Feel like Alice in Wonderland. I would choose April no question,” said Kreuziger, who underwent a lie detector test in January in a bid to clear his name.

The International Cycling Union (UCI) sanctioned the Czech rider for anomalies in his biological passport during two distinct periods — from March to August 2011 and April 2012 to the end of the 2012 Giro d’Italia, while he was riding for the Astana team.

Kreuziger finished fifth in both the 2011 Giro and 2013 Tour de France, and won the Amstel Gold Race in 2013.

After being dropped from the 2014 Tour de France, Kreuziger resumed racing after having been cleared by the Czech Olympic Committee of the charges of the charges against him last September.

But the CAS reopened the case a month later when the UCI had appealed the Czech committee’s decision.

“I’m not delaying things. These are tests from 2011. Four years and no urgency,” Kreuziger said on Twitter.

Earlier this month he finished 10th in the Tirreno-Adriatico stage race before finishing 29th in Milano-Sanremo Sunday.

The UCI is seeking a ban for Kreuziger of between two and four years and to have all his results since March 2011 erased, along with a fine of 770,000 euros ($957,000).
