Former UFC competitor and current Bellator heavyweight fighter Matt Mitrione isn’t mincing words when it comes to MMA fighters who are caught using steroids or other performance enhancing drugs.

While appearing on the “The MMA Hour” with Ariel Helwani on Monday to talk about his participation in the upcoming Bellator Grand Prix heavyweight tournament, Mitrione was asked about the possibility of facing a fighter who had previously been caught using drugs — most notably Shane Carwin.

“I believe anybody who fights an MMA fight with steroids or anabolics in their system, they should be charged with attempted murder,” Mitrione said. “If the fight actually goes on, they should be charged with attempted murder.”

Mitrione added that he would have no problem facing Carwin (or any other fighter with a history of failed drug tests), as long as they pass the current drug testing protocol leading up to the fight. He also doesn’t think he’s faced a large amount of PED-using opponents over his career, but still recognizes the significant advantage that steroids can give a cheating competitor.

“Steroids affect everything – not just muscles,” said Mitrione. “They affect cardio. They affect squeezing strength, punching strength.”If you know how to utilize it, then it’s really dangerous.”

There has never been a case where a fighter has been criminally charged for endangering the safety of his opponent after being caught using steroids.Mitrione will take on Roy “Big Country” Nelson in the opening round of the Bellator tournament, with the other first round matchups being Ryan Bader vs. Muhammed “King Mo” Lawal, Quinton “Rampage” Jackson vs Chael Sonnen, and Frank Mir vs. Fedor Emelianenko.
