The Brazilian MMA athletic commission (CABMMA) on Tuesday announced that a total of 26 drug tests were performed for all fighters at UFC Fight Night 38, and the results came back negative.

All 22 fighters on the card were tested for steroids/performance-enhancing drugs, as well as drugs of abuse such as cocaine and marijuana upon arrival to Ginasio Nelio Dias in Natal, Rio Grande do Norte, Brazil. Additionally, C.B. Dollaway and Cezar Ferreira from the night’s main card, as well as Kenny Robertson and Thiago Perpetuo from the preliminary card, were selected for random post-fight tests.

The commission also told MMAjunkie that headliner Dan Henderson, who was granted what is expected to be the final therapeutic-use exemption for testosterone-replacement therapy by the CABMMA, was tested and found to have a testosterone level under the acceptable limit.

UFC Fight Night 38 took place March 23 in Brazil. The event’s main card aired live on FOX Sports 1 following prelims on FOX Sports 1 and UFC Fight Pass.

The card featured a light-heavyweight rematch of 2011’s “Fight of the Year” between Henderson and Mauricio “Shogun” Rua. It was the Brazilian Rua who looked dominant in the opening two rounds, nearly finishing the fight in the second, before Henderson landed a massive right hand in the third round that ended the fight with a single blow.

Meanwhile, Dollaway earned an impressive 39-second stoppage of Ferreira in the night’s co-feature.
