Brutal Knockout Leaves MMA Fighter Stiff as a Board on the Canvas

In professional wrestling, Shawn Michaels is The Heartbreak Kid and The Showstopper. 

In amateur MMA, Sean Michaels broke Joe Mapanda's heart and stopped the show with a single punch.   

Michaels and Mapanda faced off in the main event of Hard Knocks 54 on Friday night in Calgary, Alberta, Canada. Michaels uncorked a pinpoint right hook that dropped Mapanda to the canvas, where he proceeded to take a quick nap. 

Michaels, who of course goes by HBK, improved to 3-1 in amateur competition. "Flash" Mapanda fizzled to 3-3.
