De Villiers tested positive for cocaine and ecstasy during a random test in December. If a second test confirms the findings of the first, De Villiers would be subject to action by the International Rugby Board and would face a possible suspension.
But at a press conference, the Stade Francais star denied knowingly taking any banned substance and insisted he had no idea how they got into his system."I have always been honest with my sport and I don't take drugs," he said. "I have always lived for my passion for rugby. I don't know how these traces got into my body. I haven't been sleeping or eating in the past 24 hours and I am asking myself thousands of questions."
De Villiers was one of 13 players from Stade Francais who were subject to on-the-spot urine tests on December 18 under the auspices of the French Ministry of Sports.
De Villiers will miss the RBS Six Nations while a B sample is carried out and will also be ruled out of the World Cup should he test positive again.
