PERTH, Australia - Former WBA light heavyweight champion Danny Green came out of retirement Sunday with a second-round knockout win over Anthony van Niekerk of South Africa.
Green improved to 26 wins, three losses with his dangerous left jab causing trouble for Van Niekerk before he finished the non-title bout with a right hook.
"I'm back," Green said. "I caught him clean and not too many people would have stood up to that shot."
It was Green's first fight since he beat Croatia's Stipe Drews to win the WBA light heavyweight belt in December 2007.
Three months later, he vacated the title. But a chance to avenge his 2006 loss to fellow Australian Anthony Mundine lured Green out of retirement.
"Anthony Mundine, you called me out ... it's lights out," Green said.
Mundine won the 2006 fight at super middleweight on points.
