The UFC Fight Night 215 event took a hit in the form of a massive cancelation, but it's safe to say that the replacement main event delivered on expectations.Just hours before Derrick Lewis vs. Serghei Spivac was set to take place, the UFC broadcast team announced that the main event bout had been scrapped due to an illness suffered by Lewis. Details about Lewis' condition are still scarce, but it was reported that the issue had nothing to do with COVID or weight cutting.ESPN MMA@espnmma"It's horrible and you feel for Derrick Lewis and you feel for [Serghei] Spivac too because this is his huge moment."@felderpaul, @bisping and @BrendanFitzTV react to the news of the Lewis-Spivac #UFCVegas65 main event being canceled.18016"It's horrible and you feel for Derrick Lewis and you feel for [Serghei] Spivac too because this is his huge moment."@felderpaul, @bisping and @BrendanFitzTV react to the news of the Lewis-Spivac #UFCVegas65 main event being canceled. https://t.co/1UPAHI3K1QAs a result, the light heavyweight contest between Kennedy Nzechukwu and Ion Cutelaba was bumped into the main event spot.Cutelaba started strong as he was able to take Nzechukwu down in the first and keep him grounded for the majority of the round.
