Ben Rothwell flagged by USADA for potential UFC anti-doping policy violation

A top heavyweight has been flagged by USADA.
Ben Rothwell is facing a UFC anti-doping policy violation stemming from a Feb. 6 sample collection, the UFC announced Tuesday. A potential violation typically occurs when a fighter fails a drug test or admits the use of a banned substance. The substance in question is not announced by the UFC nor USADA until the completion of the adjudication process unless the athlete divulges it first.
Rothwell, 35, was slated to face Fabricio Werdum at UFC 211 on M
