The representatives for welterweight world titlist Errol Spence Jr. and mandatory challenger Carlos Ocampo weren't able to make a deal by the IBF’s deadline so Thursday the sanctioning body scheduled a purse bid for March 6 at noon ET at the IBF offices in Springfield, New Jersey. Spence (23-0, 20 KOs), represented by promoter Tom Brown, is entitled to 85 percent of the winning bid and Mexico’s Ocampo (22-0, 13 KOs), promoted by Zanfer Promotions, would 15 percent. Spence (23-0, 20 KOs), 27, is scheduled to headline a Showtime card June 16 in his hometown of Dallas with Mexico’s Ocampo (22-0, 13 KOs) the supposed opponent as long as they either make a deal (which they could still do before the auction) or Spence’s camp wins the purse bid.
