British cyclist Jonathan Tiernan-Locke has been dropped by Team Sky after he failed to overturn a two-year ban for doping.
The UCI anti-doping violation was upheld by UK Anti-Doping after anomalies were found in his biological passport back in September 2012.
Team principal Sir Dave 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."
Tiernan-Locke has also been stripped of his 2012 Tour of Britain title.
