Grounded opponent - UFC/MMA
In the UFC, the definition of a grounded opponent was updated in 2017. A fighter is considered grounded when any part of their body other than their feet is touching the ground, or when they are held by their opponent in a position that would prevent them from standing up. Previously, a fighter was grounded simply by placing a hand on the mat, which was often tactically exploited to avoid knees. With the updated rule, only placing a knee or torso on the ground makes the fighter grounded. When an opponent is grounded, striking them with kicks and knees to the head is illegal, while punches remain legal. This rule exists for the safety of the fighters, as a knee or kick to the head of someone on the ground can cause serious injury.
