SOUTH WINDSOR, Conn. – Undefeated light heavyweight Oleksandr “The Nail” Gvozdyk retained his WBC world title with a bizarre TKO victory over challenger Doudou Ngumbu on March 30 before a sold-out, standing-room only crowd of some 1,350 at the 2300 Arena in Philadelphia. In his first title defense since destroying Adonis Stevenson in a fight that left the Canadian in a medically induced coma, Gvozdyk secured a fifth-round stoppage win when Ngumbu suffered a calf injury. The fifth round had the Ukrainian in complete control of the bout when Ngumbu suddenly turned his back on the champion before grabbing onto the ropes and limping back to his corner.
