At Missouri's Shamrock FC: Shock, The Hard Hittin' Hillbilly Kevin Croom gutted out a brutal arm bar attempt by Jacob Akin and came back to win. Croom would go on to the UFC, and today fights for Barek Knuckle Fighting Championship. Please note: The spike seen is not prohibited by the Unified Rules of Mixed Martial Arts. As happens in many cases in the Unified Rules, the athlete being spiked too bears responsibility. Spiking someone on their head is prohibited, if the attacking athlete has total control over the second fighter’s body. Here, Akin could have let go, but declined to. Therefore, the spike was not prohibited.
