GROUNDED FIGHTERS
A third rule change is to the definition of a grounded fighter. A fighter used to be grounded when anything other than the soles of their feet touched the canvas; a knee, a hand, a finger. Since a fighter can't be legally kicked in the head when grounded, this resulted in many "playing the game," putting a finger or two on the canvas to keep a knee from flying at their face.
The new definition is a slight tweak. Essentially the old definition still applies with an exception that for a hand to make a fighter grounded, both palms, both fists, or a palm and a fist must be touching the canvas.
As McCarthy described it, fighters are going to get kicked and hit. They're doing it now. It's dangerous for fighters to think they can play the game. "We want them to stop playing that game," McCarthy said.
Hinds said the MMA rules committee took feedback from fighters. In trial runs, when fighters got into positions where they might be grounded, "It was unbelievable."
The argument was that fighters quickly realized that having both palms on the canvas isn't good for their face and adjusted. MMA official Dan Miragliotta described the new rule as making his job "a lot easier and the fighters safer."
