Bobby Green has little to lose, but a whole lot to gain when he faces Islam Makhachev in the main event of Saturday's UFC Vegas 49 event. Can the longtime veteran pull off the massive upset and turn the UFC lightweight division upside down?

MMA Fighting's Mike Heck, Alexander K. Lee, and Jed Meshew discuss that question, along with why Makhachev isn't getting a lot of shine in his own right for taking this fight on short notice after Beneil Dariush was forced to withdraw due to an injury, the potential championship implications in the matchup, other intriguing bouts on the card, and more.
