Popular UFC heavyweight Derrick Lewis admits he has his back against the wall ahead of his UFC Vegas 65 main event bout with Serghei Spivak, but is it a do-or-die fight for "The Black Beast" in terms of being a contender in the division? MMA Fighting's Mike Heck, Alexander K. Lee, and E. Casey Leydon discuss the stakes for Lewis in Saturday's bout and what a win would do for the career of Spivak in the contender conversation. Additionally, topics include the new calmer Ion Cutelaba at the post weigh-in faceoffs ahead of his co-main event bout with Kennedy Nzechukwu, Jack Della Maddalena's ceiling in the welterweight division, the under the radar bouts on the card, and more.
