5. Alex Pereira vs. Israel Adesanya – UFC 281
Maybe not the cleanest, but surely the most important knockout of Pereira’s MMA career took place at UFC 281 in November 2022.
It took “Poatan” more than 20 minutes to find the opportunity to stop long-time rival Israel Adesanya, but when the chance came, he knocked out Adesanya in ruthless fashion.
