New Zealand rugby legend Dan Carter is one of three Racing 92 players to have been cleared by the French Anti-Doping Agency (AFLD) after a fresh investigation was launched after traces of banned substances were found in their bodies last June.

Carter, fellow All Black Joe Rokocoko and Argentinian Juan Imhoff all submitted tests showing traces of corticosteroids prednisolone following the final of the French Top 14 rugby competition on June 24.

Each attended a French Rugby Federation (FFR) anti-doping hearing in Marcoussis in October and all three were subsequently cleared of any wrongdoing.

However, the AFLD requested that all three players offer a further explanation as to how the products got into their bodies.

Their club Racing 92 and the players denied any wrongdoing and claimed they had been granted Therapeutic Use Exemptions for the substance.

"It's been a frustrating process but satisfying to finally get the final clearance from the AFLD," Carter wrote on his Instagram page.

"It has been difficult having my integrity questioned so thank you for all the support."

Their club was also delighted with the decision.

"We welcome the decision of the French Anti-Doping Agency, which without doubt has cleared Dan Carter, Juan Imhoff and Joe Rokocoko in what the media called 'the case of corticosteroids'" a club statement read.

"All this pseudo-business has cast the shame on our players and our club by spoiling our early season.

"For our part, we will simply reiterate our total confidence in our players and in Sylvain Blanchard, the doctor of Racing 92."
