UFC lightweight stars Khabib Nurmagomedov and Tony Ferguson again have been booked to fight. The bout will headline UFC 223 on April 7 at Barclays Center in Brooklyn, New York. UFC officials will formally announce the event at a Friday news conference in Boston. UFC president Dana White discussed the bout during a radio appearance Wednesday in Boston, saying he expected the fight to be in April. Ferguson holds the interim belt, and Nurmagomedov is the unquestioned top contender, but Conor McGregor still has the title in the division. White has said McGregor, who last fought in the UFC in November 2016, could be stripped of the title if he doesn’t fight again soon. The UFC 223 bout will mark the fourth time Ferguson and Nurmagomedov have been scheduled to fight. Ferguson won the interim title with a submission of Kevin Lee in December, his 10th straight victory. Nurmagomedov is 25-0 overall, 9-0 in the UFC.
