Song Yadong and Chris Gutierrez will battle it out in the main event of Saturday's UFC Vegas 83 event at the APEX, but the storylines seem to be centered on the co-main event in the UFC's light heavyweight division between Anthony Smith — who steps in on short notice — to face the surging Khalil Rountree. Could a win propel Smith to a title shot against Alex Pereira should the new champ want to stay active? MMA Fighting's Mike Heck, José Youngs, and Jed Meshew preview the promotion's final stop before UFC 296, the 135-pound headliner between Song and Gutierrez and the stakes attached to the fight, Smith possibly sneaking into a title fight with Pereira if he upsets Rountree, Andre Muniz looking to get back on track against Jun Yong Park, Tatsuro Taira's bright future, and more.
