Shocking injury: PFL fighter breaks opponent's arm with a devastating strike.

Ayder Khan, who competed in the middleweight division, finished his match against opponent Mustafa Nada in the very first round. However, this was not just any knockout; it was a true shock – Khan's devastating blow broke Nada's arm.

The climax occurred when Mustafa had to block his opponent's frontal strike. As soon as Khan's foot made contact with his arm, the camera captured in slow motion how the limb literally snapped.

The referee, of course, immediately halted the fight and awarded Khan the victory by technical knockout. Mustafa was promptly taken to the hospital by an ambulance.

It is worth noting that Ayder Khan had just made his debut in the PFL, while his opponent Mustafa Nada had already secured two early victories before experiencing this painful defeat.
