Levi Leipheimer, the American cyclist, has been sacked by Omega Pharma-QuickStep after admitting to doping while a team-mate of Lance Armstrong.
Leipheimer was one of 11 riders who testified against Armstrong to the United States Anti-Doping Agency, who accused the US Postal Service team of running "the most sophisticated, professionalised and successful doping programme that sport has ever seen".
A statement issued by Omega Pharma-Quick-Step read: "Omega Pharma-QuickStep Cycling Team announces that the contract with Mr Leipheimer has been terminated, effective immediately. We commend the rider for his open co-operation with USADA and contribution to cleaning up the sport."

Leipheimer's departure from Omega Pharma-QuickStep could allow the Belgian squad to sign Briton Mark Cavendish, if the 2011 world champion can negotiate an exit from Team Sky.
