Just in case you guys haven't heard about the MMA (Mixed Martial Arts), it is a full-contact combat sport that allows the use of both striking and grappling techniques, both standing and on the ground, from a variety of other combat sports and martial arts.
And it's usually fought one-on-one.
But not this time when they decided to do a 5 vs 5 event match. And it wasn't all fun and games. Things got real.
