The world’s biggest bareknuckle boxing promotion is back with one of its most high-profile events to date. BKFC 56 takes place Saturday at Maverik Center in West Valley City, Utah as two pairs of former UFC contenders collide and three title fights take place. Friday, all of the fighters from Saturday’s card will come face-to-face one final time ahead of their bouts. In the main event, Mike Perry and Eddie Alvarez chuck knuckles to determine the “King of Violence.” Also on the card, Jimmie Rivera battles Jeremy Stephens in a matchup between two former UFC staples.
