5. Mark Hunt vs. Roy Nelson – UFC Fight Night 52
UFC Fight Night 52 went down on September 20, 2014 from the Saitama Super Arena in Saitama, Japan.
Given the nature of the main event, no one had expected it to last too long, as legendary heavyweight sluggers Mark “The Super Samoan” Hunt and Roy “Big Country” Nelson went too battle.
A former K-1 world champion, Hunt has secured 8 of his 11 career wins by way of knockout, while Nelson, who possesses one of the most devastating right hands the sport has ever seen, has scored 14 of his 20 wins by knockout.
With both men also possessing iron chins, the bout did escape the first round, but it wasn’t long until one man unleashed a brutal bomb, and that man would be “The Super Samoan”.
Just minutes into the second frame, Hunt would land a devastating uppercut that sent “Big Country” plummeting and face planting to the canvas.
With no extra shots needed to award the stoppage, Hunt would walk off in fashion after scoring one of the best one-punch knockouts of all-time.
The scary part? This isn’t the only time that each man appears on this list.
