WINDSOR — Dearborn boxer Brian Mihtar and Ronald Hearns, son of Detroit boxing legend Tommy Hearns,  will no longer compete against each other in a boxing match originally scheduled for Oct. 9 at the Colosseum at Caesars Windsor Casino after Hearns pulled out this past week. Hearns’ camp did not provide an official reason according to Mihtar, who said potential fights with other big-name opponents have been discussed to replace Hearns. Mihtar currently holds the American Boxing Council Middleweight Title and recently signed with well known promoter Lou DiBella of DiBella Entertainment, whose roster boasts several boxing champions.
