Saturday, September 5, 2015, former Heavyweight Champion Shannon “The Cannon” Briggs (59-6-1, 52 KOs) continued his campaign for a title shot by knocking out Florida native Michael Marrone (21-5, 15 KOs) in the second round of a scheduled twelve-round bout.
Briggs retired from boxing after losing to Vitali Klitschko by unanimous decision in 2010. In 2014, he returned to boxing hoping to secure another world title shot. Since his April, 2014 return, Briggs has won all eight of his bouts with seven coming by KO. Of Briggs’ last eight opponents, Marrone is only the second to make it through the first round.
