If Khabib Nurmagomedov ’s retirement decision sticks, Dustin Poirier says the lightweight division needs to crown a new champion. It just so happens he’s about to compete in the bout that could help make that happen. Poirier (26-6 MMA, 18-5 UFC) is set to rematch former lightweight and featherweight titleholder Conor McGregor (22-4 MMA, 10-2 UFC) in the UFC 257 main event Jan. 23. It’s a marquee fight for the 155-pound weight class, but the stakes could be raised even higher. Nurmagomedov (29-0 MMA, 13-0 UFC) announced he was done with MMA competition following his title defense against Justin Gaethje at UFC 254 in October
