The fallout of the drug test failures of both Chael Sonnen and Wanderlei Silva took a step closer to being resolved after both fighters were banned by the Nevada State Athletic Commission (NSAC).

Yesterday afternoon, Wanderlei appeared before the commission with his in wife, in which he admitted to taking diuretics in order to combat a wrist injury he sustained in February. That wrist injury was a result of his scuffle with Chael Sonnen on The Ultimate Fighter Brazil 3, which had already shamed the fighter.

Speaking through his lawyer, Ross Goodman, he stated: "I want to say, first and foremost, that Wanderlei Silva has been fighting for 20 years, has over 50 professional fights, and has never failed a drug test.

"He was taking diuretics for the sole purpose of minimizing the inflammation, to decrease the water retention. He now realized that he should have submitted to the drug test. He was surprised. It was the first time in his career where something like this (happened), out of competition, somebody showed up at his gym. That doesn't negate or minimize what Mr. Silva did. He's here to apologize to the commission, and he was concerned that the diuretics would show up on his sample."

This was followed by a detailed analysis of the day from NSAC executive director, Bob Bennett, who told the commission that Silva had lead him around the gym before he escaped through an exit and got his wife to call Bennett and explain that Silva wasn't ready for the test.

Silva's case will be heard at an appeal at an unnamed date, but he will be rejected a fighter's license anywhere, meaning he's effectively suspended until further notice.

His supposed opponent, Chael Sonnen has also had his fighters license suspended, despite declaring himself retired on UFC Tonight, after he failed a random drug test ahead of his fight with Vitor Belfort, who had stepped in for Silva to face Sonnen at UFC 175.

The Orogen based fighter hasn't said anything about the commission's decision to suspend his license, but as with Silva, his case will also be held before an appeal - where they will give their final decision.

For Silva, it could push him into retirement if he's banned for long, while for Sonnen, he could come out of retirement and sit out his ban before a return a later date - as rumours suggested that he retired to avoid a suspension.

The yet to be announced dates means both fighters are in limbo but no fighter is more frustrated than Vitor Belfort, who was eventually pulled from UFC 175, after initially being booked to headline the event against Chris Weidman.
