Shawn Porter says the "fixed fight" chatter will end after Jake Paul faces Anthony Joshua in Miami, following an earlier announcement that the bout will have an official weigh-in and special safety conditions.Porter, in a TMZ interview, called Joshua an elite, active competitor and said Paul’s prior fight with a then-58-year-old Mike Tyson was not fixed but showed Tyson’s decline; he added that a Paul upset is unlikely and that "it’ll be a rough night for him."The matchup, set to stream exclusively on Netflix at the Kaseya Center under an eight-round, three-minute-round format with 10-ounce gloves and a contractual 245-pound limit for Joshua, has drawn safety debate because of a roughly 25-pound, five-inch size gap and a stacked card of title fights.
