Former four time world heavyweight champion Evander Holyfield trains during a workout at a gym in Copenhagen, Denmark. Holyfield (43-10-2, 28KOs) says he is hoping to beat Denmark's Brian Nielsen (62-4, 43KOs) in a non-title fight on Saturday and then line up a championship bout. The fight takes place in Koncerthuset. It will be Nielsen's first fight since a 2002 retirement.
