After a week off following UFC 300, the UFC returns to the APEX for UFC Vegas 91 — which will serve as the go-home show for next weekend's UFC 301 pay-per-view event. While absence does make the heart grow fonder, it's pretty clear from an interest standpoint this weekend that the UFC is playing second fiddle to BKFC, and their annual KnuckleMania fight card.Ahead of the weekend doubleheader, MMA Fighting's Mike Heck, Jed Meshew, and Alexander K. Lee preview Saturday's KnuckleMania 4 and UFC Vegas 91 events. Additionally, they'll discuss Mike Perry's return to the BKFC ring as he faces Thiago Alves in the main event, Ben Rothwell vs. Todd Duffee, the UFC headliner between Matheus Nicolau and Alex Perez, how the card stacks up from top-to-bottom on paper, and answer your questions.
