In February 2017 the International Mixed Martial Arts Federation (IMMAF) reported an anti-doping rule violation against the South African Athlete Douw Eksteen after his sample tested positive for the prohibited substance Stanozolol. After notification a provisional suspension was ordered and the Athlete failed to respond to the IMMAF communications.
Since he failed to respond the Athlete is deemed to have accepted the test result and admitted the anti-doping rule violation.
Therefore the IMMAF decides on 18 August 2017 to impose a 4 year period of ineligibility on the Athlete starting on the date of the sample collection, i.e. on 3 September 2016.
