Team Sky have cancelled the contract of Jonathan Tiernan-Locke following confirmation of his UCI Anti-Doping violation.
Anomalies were found in his biological passport relating to the 2012 season, when he was riding for the Endura team and he was investigated.
That investigation has seen Tiernan-Locke handed a two year ban, stripped of his Tour of Britain victory in 2012 and sacked by Team Sky his current employers.
Team Sky Principal Sir David Brailsford said: “Jonathan’s contract has been terminated today.
“Whilst there have been no doubts about his time with us, his doping violation - from readings taken before he joined this team - means there’s no place for him in Team Sky.
“We’ve a well-known stance on anti-doping and our action is the inevitable outcome of a violation.
“This is a team that trains, races and wins clean.”
