The NSAC (Nevada State Athletic Commission) is threatening Chael Sonnen with fines as high as $250,000 per failed drug test, if he competes as planned at Metamoris 4.

Sonnen has received a two-year suspension, for failed PED tests, which now according to journalist Jeremy Botter (as reported, via Twitter) includes a Metamoris grappling event against Andre Galvao. Metamoris is set for this weekend August 9th.

According to MMA Junkie, the NSAC informed Sonnen last week and now the retired MMA fighter is seeking legal action. If the fight is cancelled, it would be a disaster for Metamoris as this bout was the main event. They would be forced to secure another exciting on a few days notice:

“A source close to the commission, who spoke on the condition of anonymity because he was not authorized to discuss the matter publicly, today told MMAjunkie that the commission sent a letter to Sonnen this past week informing him that the grappling match violated the terms of his suspension, which was handed down in July after a disciplinary hearing on multiple failed drug tests at UFC 175.

In turn, Sonnen’s legal rep, Jeff Meyer, sent a response that challenged the NSAC’s definition of competing. At the time of this writing, it appears Sonnen will meet Galvao as scheduled; in a previous statement, Metamoris President Ralek Gracie expressed support for Sonnen despite his commission woes. Metamoris 4 takes place Saturday in Los Angeles and streams via online pay-per-view.

Although the grappling competition is not sanctioned by a state athletic commission, as it isn’t considered a combat sport in the same way as are boxing and MMA, the NSAC wants Sonnen to withdraw from the event.

Bleacher Report’s Jeremy Botter first reported news of the NSAC’s threat to Sonnen and wrote via Twitter that the fighter could be fined $250,000 per drug violation. MMAjunkie was unable to reach Metamoris organizers or Sonnen’s management.”
