On this week’s episode of What the Heck, MMA Fighting’s Mike Heck chats with Joaquin Buckley (4:50) following his viral KO win over Impa Kasanganay at UFC Fight Island 5. “New Mansa” discusses how his life has changed since this past Saturday night, if he believes he delivered the greatest knockout in UFC history, having unfinished business with Kevin Holland, and gives a response to a message on Instagram sent by James Krause. On Wednesday night, Buckley signed on to face Jordan Wright at UFC 255.
