Veteran official John McCarthy likes where MMA is currently at in terms of its ruleset and officiating. However, that doesn’t mean there aren’t things he would change. McCarthy, a retired MMA referee who helped create the Unified Rules of Mixed Martial Arts rule set in the early 2000s, wants to see the sport adopt knees to a grounded opponent – which are currently illegal. “I would love to see it knees to the head someday, but I don’t think it’s going to happen, but I would like to see it,” McCarthy told MMA Junkie Radio. “I think it would be a good thing for the sport.” Knees to a grounded opponent have long been a divisive and controversial topic in MMA.
