(Video) Physics defying Knee KO goes viral

A memorable knockout is making waves across the mixed martial arts world after a recent event by the Brazilian promotion Fight Music Show (FMS). At FMS: Fight Night 3 on April 21st in Paraná, Brazil, the middleweight co-main event between Mário Sousa and Tyago Moreira produced one of the most visceral finishes of the year so far.

The back-and-forth war was nearing the end of the first round when Sousa charged forward with a relentless combination of punches. As Moreira backpedaled to escape the flurry, Sousa launched a bone-crushing knee that caught Moreira squarely on the jaw. The impact sent Moreira crashing lifelessly to the canvas like a ragdoll dummy in a physics simulation.

Sousa followed up with some unnecessary ground strikes before the referee mercifully intervened to stop the onslaught. The scary scene left Moreira knocked out cold as medical personnel rushed to attend to him.

The knockout quickly went viral after the account shared the clip, with the footage racking up millions of views across sports and MMA fan pages. While some were surprised by the impactful finish, others praised the awe-inspiring yet disturbing display of power.

With the win, Sousa extended his current streak to 3 straight victories and improved his pro record to 19-4-1. Moreira, on the other hand, suffered his second consecutive loss, dropping his record to 15-12-1.

Whether you find the viral clip impressive or difficult to watch, there’s no denying Sousa added a memorable highlight to his career reel with this latest ragdoll physics knee knockout.
