The Ultimate Fighting Championship is often criticized in the US for its violence, but in the UK's White Collar Fighting Club (WCFC) the referees actually become part of the fight.
In a video (below) uploaded to YouTube on Sept. 24, a hapless referee was trying to separate two fighters, but the bald fighter ignored the ref's pleas.
Suddenly, another referee, Lee Ambler jumped into the ring to take down the disobedient fighter via body slam.
After holding the fighter down for some time, the match was cancelled, which was met with resounding boos from the audience.
Outside the ring, Amber and the bald fighter exchanged words.
According to their YouTube page, the WCFC is part of Cage Amateurs UK.
