Érik Morales
In addition to McCullough's dogged, relentless attacking style, he was renowned for his durable chin, having fought two of boxing's biggest punchers in Naseem Hamed and Érik Morales, and going the full distance with both of them. During his bout with Morales in 1999, HBO commentator Larry Merchant joked, "If you look in the dictionary, under 'Tough Irishman', you'll find a picture of Wayne McCullough". McCullough was never once knocked down in his professional career. He also stopped the late Arturo Gatti as an amateur.
