Mr. Hasim Rahman JR, on the other hand, is the son of a legend who fought on Mike Tyson's undercard. On Saturday, the cruiserweight hopeful, who had a falling out with Floyd Mayweather, will meet ex-UFC fighter Rashad Coulter. It comes after Brit Viddal Riley was forced to leave the game due to an injury, with Rahman Jr coming in. He has never been defeated and is rated No. 1 by the WBC. Rahman Jr started his career at the age of 15 with a record of 13-0. He won all his fights via knockouts. This included wins over future world champions including Bryant Jennings and Andrew Lewis. In 2011, he met Floyd Mayweather Jr during one of his exhibitions. The fight was stopped in the fourth round due to a cut from a headbutt. Mayweather praised Rahman Jr for being brave enough to take the fight against him. However, later that year, Rahman Jr dropped out of his next exhibition due to an ankle injury. He was replaced by British boxer Viddal Riley. Since then, he has not fought again and is now focusing on becoming a pro wrestler. As for his father, he is also a famous boxer who has held the WBA super lightweight title twice. He has a record of 31-3-1 with 25 KOs. After retiring from boxing, he moved to America where he became a US citizen. Rahman Jr has two siblings named Suleiman and Samia.
