Mirko ‘Cro Cop’ Rips ‘Fat, Disrespectful’ Roy Nelson for PED Speculation Ahead of Bellator 200

Mirko Filipovic had some choice words for Roy Nelson after “Big Country” speculated that “Cro Cop” might be on performance enhancing drugs when they square off at Bellator 200.

Filipovic and Nelson will meet in a heavyweight tilt on May 25 at the SSE Arena in London. Shortly after the rematch was announced – Nelson defeated Filipovic via third-round TKO at UFC 137 – Nelson told MMAjunkie.com that he thought the 43-year-old Croatian knockout artist could be using “special supplements” to propel him to his current winning streak.

On Sunday, “Cro Cop” fired back in a Facebook post.

“Dear Roy Nelson, you don’t have to worry that I’m using any ‘special supplements’ as you claim,” Filipovic wrote. “The only ‘special supplements’ I’m using is [two] hard and bloody trainings per day, five days a week. And I will be tested, like all others, during preparations for the fight and before and right after the fight.

“So you can be calm and start thinking of some good excuse after I beat up your fat disrespectful ass. You have enough time to May 25 and do me a favor please, and shave that disgusting beard, look like professional fighter and show respect to your opponent. Good luck!”

Filipovic was suspended for two years by USADA for his use of human growth hormone prior to a scheduled bout against Anthony Hamilton at UFC Fight Night in Seoul, South Korea, in November 2015. The Pride Fighting Championships veteran announced his retirement shortly before the suspension, but ultimately ignored the sanction to return to fight in Japan for the Rizin Fighting Federation.

Overall, Filipovic has won eight consecutive contests since 2014, including triumphs over the likes of Gabriel Gonzaga, Satoshi Ishii (twice) and Muhammed Lawal.

Mike Mazzulli, the president of both the Association of Boxing Commissions and the Mohegan Tribe Department of Athletic Regulation, will oversee drug testing at Bellator 200. Bellator 200 will air via tape delay in the U.S. on the Pararmount Network at 9 p.m. ET/8 p.m. CT. The card will also include a middleweight championship clash between and Gegard Mousasi.
