On Friday, the Nevada State Athletic Commission released the results of the drug tests taken at UFC 155.
In an email from the Executive Director of NSAC, Keith Kizer noted that all 24 fighters were tested for illegal/banned substances and they all came back negative.
UFC 155 went down on Saturday December 29, 2012 from the MGM Grand Garden Arena in Las Vegas, Nevada.
In the main event we saw the heavyweight championship up for grabs, and Cain Velasquez reclaimed it when he dominated Junior dos Santos from bell to bell.
Also on this year-end card in the co-main event slot two of the lightweights best put on a show for the ages, as Jim Miller took home the judges nod against Joe Lauzon.
