All 20 UFC Fight Night 29 fighters passed their drug tests.
Brazilian MMA Athletic Commission (CABMMA) tested every fighter before their bouts on Oct. 9 in Barueri, Brazil. After the bouts, the headliners – Demian Maia and Jake Shields – were tested again, in addition to four other randomly selected fighters.
Four of the 20 fighters on the card had tested positive for banned substances before in the UFC – Jake Shields, Thiago Silva, Joey Beltran and Rousimar Palhares –, but all results came back negative after UFC Fight Night 29.
