Donald Cerrone can still feel the agony that was attached to his first career loss by strikes. At UFC 249, he gets the chance to numb that pain. Cerrone’s first knockout loss in MMA competition came courtesy of a devastating Anthony Pettis body kick less than three minutes into their bout at UFC on FOX 6 in January 2013. It was a key matchup for the lightweight division at the time, and now more than seven years later, the pair run it back at UFC 249. Much has changed since the initial clash.
