Six fighters who underwent testing for performance-enhancing drugs and drugs of abuse tested clean following UFC 127. UFC Vice President of Regulatory Affairs Marc Ratner today e-mailed the drug-test results to MMAjunkie. The event was overseen by the Combat Sports Authority of New South Wales, though the UFC independently conducted the testing. UFC 127 took place Feb. 27 at Acer Arena in Sydney, Australia, and aired live on pay-per-view. Headliners B.J. Penn and Jon Fitch fought to a majority draw in a welterweight bout. The UFC tested both Penn and Fitch, as well as four others at random on the 12-fight card. The names of the fighters tested at random were not disclosed. All tested negative for drugs of abuse (such as marijuana and cocaine), as well as anabolic steroids and other performance-enhancers. The main event ended in disappointment after Penn took an early lead in the opening frame before Fitch charged back in the second. The two then fought a competitive fight, but it was Fitch who dominated the third round and earned a 10-8 score from two judges. Those scores resulted a majority draw. Michael Bisping's TKO win over Jorge Rivera in the evening's co-main event was marred by an illegal – and some would say intentional – knee and a nasty post-fight scene in which he spit in the direction of Rivera's cornermen.
