After a big win in the main event at UFC Fight Night 239, [autotag]Marcin Tybura[/autotag] is making moves at heavyweight.

He’s won eight of his past 10 fights with setbacks against current interim champion Tom Aspinall and former Bellator champ Alexander Volkov, and he moves to No. 7 on the charts. Tuivasa took a slight tumble and is on a four-fight skid, but the losses have been to some of the elite in the division.
