We’ve got you covered with all of tonight’s UFC Rio results, including the lightweight main event between Charles Oliveira and Mateusz Gamrot.
Oliveira (35-11 MMA) returns to action for the first time since suffering a brutal knockout loss to Ilia Topuria at the UFC 317 event in June. Prior to that setback, ‘Do Bronx’ was coming off a dominant decision victory over Michael Chandler at UFC 309 last November.
Meanwhile, Mateusz Gamrot (25-3 MMA) was most previously seen in the Octagon at the UFC Vegas 107 event in May, where he scored a unanimous decision victory over L’udovit Klein. That win was preceded by a split-decision loss to fellow lightweight contender Dan Hooker.
