The World Series of Fighting experienced a bad time Saturday night, as the New Jersey Athletic Commission cancelled a planned middleweight contest between Elvis Mutapcic and Jesse Taylor at WSOF 5.

The bout was suppose to help determine the finals in the middleweight tournament to crown a champion, but the commission called it off after Mutapcic was seen taking medication backstage that was not checked prior.

“There were some prescriptions that weren’t given to our doctors during the physicals and that weren’t approved by us, the commission. So since we don’t know what they are and what they do, we cancelled the fight,” read a statement released by the commission. “We can’t take that chance to have that fight go off, so those things need to be looked at, and they need to be talked about. We just feel that we’re not going to have a fight in New Jersey when we don’t know what someone is taking.”

WSOF president Ray Sefo stated, “It is sad to see this happen. I’ve been in martial arts for 25 years and have never seen anything like this. Elvis has been training for this fight for 10 weeks. But the commission has made its decision and we have to live with it. Because this was an issue with the fighters manager, both fighters will receive their show money.”

Mutapcic was shocked by the decision. He has won five straight, including a victory over Sam Alvey earlier this year.

“I really don’t know what happened, what she saw. She might have been taking some medication, herself. I put in a good 10-week training camp,” the fighter said. “I worked my ass off. I know Taylor’s ready. I’m not sure if she misstated me for my manager, who has a heart prescription. He was the one that had it. We’re all dressed the same – same T-shirt, same hat. I mean, there’s four of us, and she’s pointing me out, that I took it. I say I’ll take a blood test. I’ll give a hair sample if they need it. I’ve got nothing in my system. I’m completely clean.”
