A soccer kick, also known as a soccer ball kick or PK (penalty kick) in puroresu and shoot fighting, and as tiro de meta in vale tudo, is a reference to a kick that is similar to kicks used in association football. It is the colloquial term for a kick performed against a prone, kneeling, rising or supine opponent by a fighter who is in a standing or semi-standing position, to any part of a downed opponent.[1] The technique is banned under the Unified Rules of Mixed Martial Arts; however, other rulesets, including the ones used by Pride Fighting Championships do permit them. Soccer kicks have been regularly discussed as to potential damage. There has been a regular debate on the usage of them within MMA. Some MMA fans and fighters support them while a fight doctor and politicians have opposed them.
