Jonathan Tiernan-Locke: Former boss backs rider

Endura Racing team manager Brian Smith says he is still "100% behind" British cyclist Jonathan Tiernan-Locke, despite the 28-year-old facing disciplinary proceedings amid allegations of anti-doping violations.

Talking to BBC Radio 5 live, Smith said that "common sense" told him that Tiernan-Locke, who strongly denies any wrongdoing, was not a doper.

Tiernan-Locke used to ride for Endura before moving to Team Sky.
