5. Steven Thompson KOs Johny Hendricks (February 6th 2016)
In the pre-USADA era Johny Hendricks was a UFC Welterweight Champion, but now the guy doesn’t even have enough testosterone to grow his beard out. Granted this KO came from Stephen “Wonderboy” Thompson, who absolutely will be Welterweight Champion at some point.
When these two met in the main event of UFC Fight Night: Hendricks vs. Thompson, it was a contest between one guy on his way up and the other on his way down. Thompson would go on to win his next fight against Rory MacDonald, while a clean shaven Hendricks would drop his next fight at UFC 200 to Kelvin Gastelum.
