BERLIN -- Germany's Patrik Sinkewitz is accusing cycling's governing body of misleading him about testing positive for human growth hormone.
The rider says on his website that he was told by the ruling organization that a "substance" was found in his body. He insists this is not true, and that a blood sample is being investigated.
Sinkewitz says he opened his own investigation after the "initial shock" over the positive test for HGH, a first in cycling. He hopes the issue can be cleared up and his "innocence proven."
Sinkewitz was suspended March 18 when the UCI announced he had tested positive for HGH at the Grand Prix di Lugano on Feb. 27.
He could face a lifetime ban because he already has served a one-year doping suspension.
