ONE Championship made its United States debut Friday in Broomfield, Colo., just outside Denver.
ONE Fight Night 10 was headlined by former UFC flyweight champion Demetrious Johnson as he defended his 135-pound title in a trilogy match against Adriano Moraes.
Also on the card, former UFC star Sage Northcutt returned to action after four years away from competition as he battled Ahmed Mujtba at 1STBANK Center.
