All eight fighters who underwent drug testing at February's UFC 144 event tested clean for performance-enhancing drugs and recreational/drugs of abuse.
UFC Vice President of Government and Regulatory Affairs Marc Ratner, confirmed the drug-testing results with MMAjunkie.com (www.mmajunkie.com).
UFC 144 took place Feb. 26, at Saitama Super Arena in Saitama, Japan. The main card aired on pay-per-view (on Feb. 25 due to the time difference), and FX and Facebook carried the prelims.
Because no regulatory body was available, the UFC acted as its own under the direction of Ratner.
