UFC officials announced the bout on Thursday.
Cerrone (24-6, 1 NC), a fan-favorite who campaigned hard for a spot on the card following the recent injury to UFC light heavyweight champion Jon Jones, now rides a four-fight hot streak into the contest, having finished Evan Dunham, Adriano Martins, Edson Barboza, and Jim Miller in succession. All four of Cerrone's wins arrived inside two rounds, and all four earned him post-fight bonuses.
Green (23-5), meanwhile, enters the contest fresh off the biggest win of his career. The 27-year-old captured a split decision over former Strikeforce lightweight champion Josh Thomson in July, putting an exclamation point on his current eight-fight win streak.
