Today the two men took part in their weigh in for the contest, and both came in comfortably under the 147lb Welterweight limit.
Pacquiao, who has won world titles from Flyweight to Light Middleweight, was the lighter man and looked the smaller fighter at the weight in but seemed really relaxed and comfortably. Horn, the slightly taller man, seemed calm is on the biggest stage of his career and going up against a true boxing icon.
If Pacquiao wins, as is expected, there is talk that his next defense could be against unbeaten Russian hopeful Konstantin Ponomarev (32-0, 12).
