Update: The original headline was "Anderson Silva's win over Nick Diaz switched to a no contest," based on comments made by NAC (title) Bob Bennett to Brazil's Globo. We have changed it to reflect clarifications from the NAC.

Things have gone from bad to worse for Anderson Silva. After an impressive win against Nick Diaz at UFC 183, the UFC announced that the former long term champion had tested positive for two performance enhancing drugs in his Jan 9th pre-fight drug test. While Silva adamantly denies any wrong doing NAC executive director Bob Bennett predicts that Silva's victory will likely be overturned at the next commission hearing. In light of the failed drugs test, the bout result will now be changed to a no contest which could have massive financial repercussions for Silva.

Speaking to Brazilian newspaper Folha Bennett said :

'Yes, it will be ruled a NC (no contest). I don't know if he will receive the win bonus after this change. That's UFC's call, but a percentage of his purse will be held because of this episode.'

Here's the Bloody Elbow Tete-a-Tete crew, to weigh in with their thoughts on Silva's drug test

Anderson Silva now faces the prospect of a substantial fine as well as a long term suspension and as Bennett hinted the UFC might also revoke his win bonus which is likely sizeable.

With this latest development Silva's record is now without a win since October 2012 and it seems unlikely that he will have the opportunity to add to his win column in the foreseeable future. Stay tuned to Bloody Elbow for more news and updates as this story continues to unfold.
