Former All Blacks Dan Carter and Joe Rokocko have tested positive for steroids, according to a report in French newspaper L'Equipe.
L'Equipe is reporting the two former All Blacks, along with former Pumas winger Juan Imhoff, were found with traces of steroids in their urine samples after the French 14 final in June.
But NZ Herald reports that the pair have the correct therapeutic use exemptions (TUEs) to use certain types of prescribed medication.
The initial results from Carter, Rokocoko and Argentine Imhoff reportedly showed traces of corticosteroids.
It is claimed France's anti-doping agency (AFLD) conducted a urine test on both sets of players.
Racing won the match 29-21 at the Nou Camp with Rokocoko scoring the only try.
Carter was named Man of the Match having scored 15 points with five penalties.
