(Bowles in happier times) In case you missed it, nation, not all UFC 160 fighters passed their post-fight drug tests. Nevada State Athletic Commission (NSAC) Executive Director Keith Kizer let us know yesterday that former champion Brian Bowles has some ‘splaining to do. Regarding UFC 160, Kizer wrote in an email that All athletes tested.  All results negative, except Brian Bowles tested positive for an elevated T/E ratio (> 20).  A complaint will be forthcoming. First off, let’s just highlight the fact that Kizer said that all fighters on the UFC 160 card were tested. Used to be that only a select few were ever tested following bouts, you might remember. For some time now, however, the NSAC has been testing all fighters on a given card. Ain’t no Canadian loopholes in Nevada, we suppose. Back to Bowles – The failed test is just an extra bummer for him. He returned to action for the firs time since 2011 at UFC 160 and lost via TKO to George Roop. No one seems to really be able to truly explain the precise significance of what elevated testosterone to epitestosterone ratios mean, but we do know that athletes can sure get in trouble for having them. A complaint from the NSAC will soon be filed against Bowles and his license to fight is presumably temporarily suspended until he has a hearing before the regulatory body to explain himself and the test results. At that point, the commission could decide to do any number of things with Bowles from reinstating his license immediately to suspending him for a specific period of time and fining him a portion of his UFC 160 purse. Bowles has now lost two in a row. Thus far, he hasn’t appeared to comment publicly on the test results.  We’ll keep you posted as more news develops. – Elias Cepeda
