WBC light heavyweight champion Adonis Stevenson is working hard for his upcoming defense against Sakio Bika, who previously held the WBC title at super middleweight. The CBS televised fight takes place on April 4th from the Pepsi Coliseum in Quebec. Stevenson has vowed to become the first boxer to knock Bika out. The winner of the fight will have to defend the title, per the recent order of the WBC, against mandatory challenger Sergey Kovalev, who also holds the light heavyweight titles of the WBA, WBO, IBF and recently picked up the WBC's Diamond belt at 175-pounds.
