In May 2018 UFC fighter Vitor Belfort was knocked out by Lyoto Machida. That was the reason that Belfort decided to hang up his fighting gloves. But the octagon beckoned again and now we will be seeing Belfort once again but in the arena of One FC this time. The date and opponent will be announced later. There are now 4 popular UFC fighters in One FC. Aside from Belfort, Eddie Alvarez and Demetrious Johnson jumped the UFC fence and followed by Sage Northcutt.
