The Comissao Atletica Brasileira de MMA (CABMMA) today announced that drug tests for UFC 179 came back clean.

In a prepared statement obtained by MMAjunkie, CABMMA said all competitors were tested for performance-enhancers and drugs of abuse. Additionally, the event’s main event competitors, featherweight champ Jose Aldo and Chad Mendes, were tested for human growth-hormone and erythropoietin (EPO). Co-main event fighters Phil Davis and Glover Teixeira were tested for EPO.

UFC 179 took place at Maracanazinho Gymnasium in Rio de Janeiro, Brazil. The event’s main card aired live on pay-per-view following prelims on FOX Sports 1 and UFC Fight Pass.

CABMMA, which is backed by the industry-leading promotion, is now testing for additional substances in the wake of enhanced testing being employed for major fights in the U.S.

Recently, though, the commission exerted its authority when it found a common steroid in UFC fighter Piotr Hallmann, who was flagged for drostanolone in the wake of his UFC Fight Night 51 loss to Gleison Tibau. The commission upheld a nine-month suspension following Hallmann’s appeal.

In UFC 179’s main event, champ Aldo retained his belt in a thriller opposite Mendes. The two earned “Fight of the Night” honors. In the co-headliner, Davis outpointed Teixeira to get back in the running for the light heavyweight title.
