Islam Makhachev and Alexander Volkanovski will battle it out in a champion vs. champion matchup for the #UFC lightweight title in the main event of #UFC284 — a fight that will determine who is the best pound-for-pound fighter in the world today. If Volkanovski, the current featherweight champ gets it done and pulls off the upset, where will the win rank all-time? Join MMA Fighting's Mike Heck and Alexander K. Lee, along with UFC featherweight Calvin Kattar as they discuss the high stakes main event for Saturday's pay-per-view event, where each division goes depending on who leaves Perth victorious, and more. Additionally, they'll discuss the interim 145-pound title fight between Yair Rodriguez and Josh Emmett, other notable matchups on the card, and take viewer questions at the end. Show goes LIVE Friday at 3 p.m. ET / Noon PT. Join this channel to get access to perks: https://www.youtube.com/channel/UC4f1JueVgo5t9HSmobCRPug/join Subscribe to MMA Fighting on YouTube: http://goo.g
