The vacant welterweight championship is on the line when Oktagon 84 kicks off live from Ostravar Aréna in the Czech Republic.
Former lightweight titleholder Ronald ‘Rony’ Paradeiser stepped into the main event spotlight on Saturday, looking to claim a second belt under the Oktagon MMA banner. Standing in his way was ex-welterweight king Kaik Brito, who vacated the title prior to an appearance on Dana White’s Contender Series in 2023. Now, the Brazilian is back and ready to reclaim the crown he never lost.

In the co-main event, another former welterweight champ — David Kozama — looked to snap a three-fight skid against Jozef Wittner, a PFL alum returning to the promotion for the first time since 2020.
