UFC light heavyweight Stanislav Nedkov appeared to be on his way to remaining unbeaten earlier this month in a bout with Thiago Silva at UFC on Fuel 6, as the 31-year old was up on the scorecards entering the third round of their rumble before getting taken down and submitted. Though he accepted the defeat gracefully, it turns out Nedkov had some suspicions about his adversary’s performance and saw them confirmed to an extent last week when Silva tested positive for marijuana metabolites after the outing.

“I had serious doubts whether Thiago would be clean,” revealed Nedkov in an interview with TATAME, showing an obvious lack of surprise about Silva getting popped.

Nedkov also explained he has no problem with marijuana being labeled as a performance enhancing drug despite the protests of many in the MMA community about it’s actual effects in relation to giving users a competitive edge.

“I consulted some specialists they told me that marijuana increases the adrenaline in the body, and also expands the lungs and increases the flow of oxygen muscles, which helps in the resistance. This, in addition to hiding the use of anabolic steroids, which have greater punishment than marijuana,” explained Nedkov, alluding to Silva’s history with steroids.

While the UFC’s decision to suspend Silva for six months and change the bout’s result to a No Contest were welcome punishments, the Bulgarian brawler still isn’t happy about the situation because he ultimately didn’t come away with a victory. However, he plans to use the experience to improve in certain areas, finding the silver lining around an otherwise dark cloud.

“Although he used banned substances, I learned a lesson and will not let (the same mistakes) happen again in my next fight,” said Nedkov. “This fight will make me a better fighter.”
