After junior lightweight world titlist Gervonta Davis knocked out late replacement Hugo Ruiz – who had stepped in for injured Abner Mares – in the first round on Feb. 9 in Carson, California, promoter Leonard Ellerbe of Mayweather Promotions said Davis would have a Baltimore homecoming defense in his next fight this summer. That is precisely the plan. Davis will headline a Showtime card on July 27 at the 14,000-seat Royal Farms Arena in Baltimore, a source with knowledge of the plans told ESPN on Tuesday. There is no set opponent yet but there has been chatter about Davis’ second defense coming against former titlist Yuriorkis Gamboa, who has won three fights in a row.
