(Props to CP reader Jason Jenkins for delivering both the video and the knockout-to-end -all-CP-reader-knockouts.) 

We’ve only said this once in the history of CagePotato, but thank God for Facebook. If not for this social networking device, we would have never come across CP reader Jason Jenkins’ incredible knockout that occurred over the weekend at Ultimate Impact K1 in Gloucester, Massachusetts.

The video, which Jenkins passed along to us just a couple of hours ago, features the “Grasshopper” going full on Edson Barboza on his opponent, Phill Savage, delivering an incredible spinning wheel kick KO less than a minute into their fight. The fact that he throws an extra spin into his kick for good measure makes the knockout all the more impressive. Seriously, it is probably the coolest finish we’ve seen since Cairo Rocha’s Capoeira style destruction of Francisco Neves back in December of 2011.

The brutiful KO awaits you after the jump. 

From grappling we move straight to kickboxing, just to make sure we cover both ends of the spectrum of things that are not MMA, but are pretty close.  Following his decision loss to Joe Warren at Dream.9, "Kid" Yamamoto stepped back into the K-1 ring on July 13 for the first time since 2005 to try and reverse his fortunes.  That effort proved…painful.  Korean fighter Jae Hee Cheon knocked Yamamoto out cold with a brutal right uppercut-left hook (man, can’t you just hear Bas Rutten shouting that?) combo in the first round.  It’s his third K-1 loss in four tries, so hopefully it will convince him to stick with MMA, where he’s been far more successful.  It’s either that or else get used to having periodic gaps in your memory.
