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.
