Two men throwing wild swings, trying to get through each other’s guard, pushing each other into the ring ropes. The ring doctor pauses the fight for a moment and inspects the fighter’s face. His ears and eyes are swollen and blood is oozing from several cracks in the skin, especially on his exposed ankles. But the fighting continues until the fighters are covered in gaping wounds and cuts. Blood and sweat run down their arms, drip onto the ring floor and turn the organizer’s logo red. This is the Bare Knuckle Fighting Championship (BKFC), which successfully turns the so-called bare knuckle, boxing without boxing gloves, into a major sport.
