Thursday afternoon in California Anderson Silva and Michael Bisping participated in the ‘UFC Fight Night: London’ early open workouts ahead of their February 27th main event scrap.

While the event went off without a hitch, the pair exchanged some heated words prior to the workout part of the event.

It started with the pair exchanging greetings before Bisping jokingly told Silva to leave the viagra out of this training camp, an obvious diss at Silva’s failed drug test last year.

Silva responded in a semi-joking manner and things just escalated from there before people separated the pair.
