LAS VEGAS - Undefeated former two-division world champion Terence Crawford is universally recognized as one of the top boxers on the planet and he is moving up in weight to seek a world title in a third weight division. In his way is the tough-as-nails welterweight world titleholder Jeff Horn, who is also unbeaten and quite confident that he can pull off another monumental upset after controversially outpointing the great Manny Pacquiao to claim a 147-pound belt last July before 51,000 spectators at Suncorp Stadium in his hometown of Brisbane, Australia.
