Cyclist Who Testified Against Floyd Landis Pleads Guilty
Papp pleads guiilty to two counts of conspiracy to sell Human Growth Hormone, EPO.
Tour de France victory showed abnormally high testosterone levels. Landis called it another attempt by the lab to fabricate evidence against him.
In the Leogrande case in 2008, USADA attorneys introduced cell phone records showing more than 270 calls and texts between Papp and Leogrande, and pictures of Leogrande holding vials of EPO at Papp's home.
Leogrande also received a two-year doping ban for using the drug after suing to prevent the USADA from testing his backup urine sample after his original sample was deemed "clean" because of technicality.
Papp faces up to five years in prison on each of the conspiracy charges when he's sentenced June 25.
