Ruiz even heavier for his heavyweight rematch with Joshua

World heavyweight champion Andy Ruiz Jr. will be nearly 50 pounds heavier than Anthony Joshua for their title rematch on Saturday in Saudi Arabia. Ruiz weighed in at 283 pounds (128 kilograms) on Friday - about 15+ pounds (7 kilograms) more than he was for the first fight in New York in June when he delivered one of the biggest heavyweight upsets in recent history. ''He's a big boy, isn't he?'' Joshua said of Ruiz after the Briton weighed in at 237 kilograms (107+ kilograms), ensuring he will fight at his lightest weight in five years as he tries to reclaim his WBO, WBA and IBF belts.
