The Nevada State Athletic Commission drug tested every fighter at last weekend's UFC 155 event in Las Vegas, and the commission got back the results on Friday.
All fighters tested negative for performance enhancing substances, as well as for drugs of abuse. NSAC executive director Keith Kizer informed MMATorch of the results Friday afternoon.
UFC 155 was the UFC's final event of 2012, and was capped off by Cain Velasquez recapturing the UFC Heavyweight Championship in a five round beating of the man who took that belt from him, Junior dos Santos.
