Derrick Lewis delivered a sensational knockout of Rodrigo Nascimento in the main event of Saturday's UFC St. Louis fight card, and then put on a show in his post-fight celebration. Lewis has put himself above the rankings in a lot of respects as people just want to see him in fun fights — but following another stoppage, what should be next? On an all-new edition of On To the Next One, MMA Fighting's Mike Heck and Alexander K. Lee discuss what could be next for "The Black Beast" following this past weekend's victory. Additionally, future matchups are discussed for Joaquin Buckley after his co-main event win over Nursulton Ruziboev — and subsequent callout of Conor McGregor — Carlos Ulberg following his 12 second knockout win over Alonzo Menifield, along with fellow main card winners Diego Ferreira, Sean Woodson, Waldo Cortes-Acosta, and more.
