'Big' John McCarthy says Alex Pereira has it all wrong with Herb Dean controversy in UFC White House fight

Officiating has been a hot topic throughout the MMA world since Alex Pereira suffered a second-round knockout loss to Ciryl Gane at UFC Freedom 250 at the White House. In the aftermath of the now-controversial finish, Pereira has campaigned vigoriously for referee Herb Dean's removal from the sport.

Veteran referee “Big” John McCarthy, however, doesn't believe the backlash is justified. Pereira's main complaint pointed to the nature of several Gane strikes, which he believes illegally landed on the back of his head. Dean responded to the claims with an explanatory video outlining what constitutes the illegal back-of-the-head zone. Speaking on Tuesday's edition of "The Ariel Helwani Show," McCarthy reaffirmed that Dean's explanation and citation of the "two-inch" strip surface area was accurate.

"Not one of those was an illegal shot," McCarthy told Uncrowned. "That is not an illegal elbow to the back of the head. That is a legal shot right there, because that would be hitting right where it's even past the crown of the head. So that's a legal shot, the back of the head.

"Here's the problem — we have all these different commissions, we have different groups, we have different people. And when the unified rules was put together, I made it as open as I could with what was occurring at the time, as far as what the back of the head is. We were coming into the world of boxing — the commissions were very comfortable with the boxing world. They were not comfortable with MMA. So they wanted to go with headphones, which is boxing — that is what the back of the head is. Medically speaking, they're right — it's what the back of the head is. But boxing is a 180-degree sport, meaning we cut that boxer like the headphones straight down, and straight down the sides and at the waist. That's your legal areas. You can't touch their back, you can't do anything. MMA is a completely different sport. MMA is a 360-degree sport.

"Let's go back to the early days, there was no back of the head, OK?" McCarthy continued. "They were allowed to hit everywhere that was possible. We didn't have any complaints. We didn't have people getting hit and going, 'Oh, oh my God.' They knew they could be hit. Now, again, when you believe that you can't be hit somewhere, and you get hit there right away, it's an attention-getter. And you're thinking, 'Hey, you can't hit me there.' So I'm not blaming the fighter in any way. But the back of the head starts at the crown of the head — that is meaning that all of this on top, all of this is good."

The controversy raised by Pereira has not only put a target on Dean’s performance as a referee, but also added fuel to accusations that Gane is a dirty fighter. Before their White House clash, Gane saw his prior title fight with Tom Aspinall end in a no-contest last October after accidental eye-pokes from Gane rendered Aspinall unable to continue.
