The biggest fight in the history of the UFC lightweight division is finally here, as unbeaten world champion Khabib Nurmagomedov puts his title on the line against Tony Ferguson in the main event of UFC 249 at Barclays Center in Brooklyn on April 18. Winner of 12 in a row, Ferguson has left no doubt that he's ready to challenge Nurmagomedov, whose perfect 28-0 record includes wins over Conor McGregor and Dustin Poirier. Plus, one of the most memorable strawweight fights of 2019 will get a rematch when former world champions Jessica Andrade and Rose Namajunas meet again.
