Bellator 277 is set after all fighters made weight ahead of its stacked card topped by two title fights.
The main event will be a championship rematch between A.J. McKee and Patricio Freire. McKee (18-0) stayed perfect in his mixed martial arts career by submitting Freire (32-5) in under two minutes to claim the Bellator MMA featherweight title. Now, "Pitbull" will look to reclaim the belt he once held. Both fighters easily made weight, with "Mercenary" weighing 144.4 pounds, while Freire stepped on the scale at 144.6 pounds.
The co-main event is equally important, as Vadim Nemkov will defend his light heavyweight throne against Corey Anderson to conclude the 205-pound tourney.
