Anthony Joshua is the IBF World Heavyweight champion after knocking out Charles Martin in the second round at London's O2 Arena. Joshua is unbeaten in his 16 professional fights, and made short work of his opponent with a sharp right, which floored the American. Fellow British heavyweight champion, Tyson Fury, posted on twitter saying his rival looked "slow and ponderous", while boxing legend Frank Bruno praised AJ saying "your country is proud of you." Martin may be regretting his decision to wear a crown and cape before the fight, which was Joshua's fifteenth win inside three rounds.
