Team Sky has fired British cyclist Jonathan Tiernan-Locke after he was suspended for two-years from using performance enhancing drugs.

According to the International Cycling Union, Tiernan-Locke has been banned for two-years because of discrepancies in his Athlete Biological Passport. He will also lose his titles from the 2012 Tour of Britain and the 2012 UCI Road World Championships, when the discrepancies were found.

He will be ineligible to race until December 31, 2015.

Sir Dave Brailsford, the team principle for Team Sky said that the team has a well-known anti-doping stance, according to a statement.

“This is a team that trains, races and wins clean.”

Team Sky has been aware of the issues since September 2013. Tiernan-Locke has not raced or trained with the team since he was notified of the violation on December 16 2013.

He was considered the next big British cycling star following Bradley Wiggins and Chris Froome, who have won the past two Tour de France’s while competing for Team Sky, respectively, according to the AP.
