The American cyclist Levi Leipheimer has been sacked by the Quick-Step team after admitting he took banned substances as part of the US Anti-Doping Agency investigation into doping in the sport.
The 38-year-old Leipheimer was one of 11 former team mates of Lance Armstrong to testify against the seven-times Tour de France winner who was stripped of those titles and banned for life by USADA in August.
Leipheimer's best results include finishing second in the 2008 Vuelta and third in the 2007 Tour de France. He also won a road time trial bronze at the 2008 Beijing Olympics.
