( CNN ) -- South African rugby union stars Chiliboy Ralepelle and Bjorn Basson are free to play again after their bans for testing positive for a prohibited stimulant were scrapped . The pair were charged after South Africa 's test match against Ireland in Dublin back in November 2010 after testing positive for a substance known as methylhexaneamine ( MHA ) . Ralepelle and Basson were immediately banned from rugby and sent home from the tour . The supplement was supplied to them by the South African medical team . But at a hearing in Cape Town , their advocate Attie Heyns successfully challenged the ban on the basis that MHA had been downgraded by the World Anti Doping Agency ( WADA ) . Ralepelle told the official South African Rugby Union ( SARU ) website : `` Finally the facts are out there and people can see that we were not guilty and are not doping cheats , '' he said . `` We were only doing what the large majority of professional rugby players around the world do by using a supplement . `` Bjorn and I were the unlucky ones to be tested on the day and to have had to go through the trauma of the past two-and-a-half months . We 're both now just looking forward to playing again and closing this chapter once and for all . '' The South African team , known as the Springboks , has now changed its approach to supplements and will not be issuing any to team members . The chief executive of SARU Jurie Roux added : `` This verdict completely quashes any idea that either the players or the team were guilty of any attempt to cheat . No responsibility attaches to the players at all . `` The banned stimulant was in a supplement given to the players in the warm-up before the test against Ireland and is a product that has been used by the Springboks before -- without any adverse analytical findings -- and is used by other professional and national teams in both hemispheres . `` That the players subsequently tested positive for a banned stimulant was an enormous shock to the Springbok team , management and to SARU and I am most sorry that the players have had to endure the stress and stigma attached to a failed dope test . `` Hopefully this verdict will have laid to rest any idea of any wrong doing on their part . ''
