A major upset saw Anthony Joshua miss out on the chance to become three-time world heavyweight champion on Saturday night, as he was knocked out by British rival Daniel Dubois in the fifth round.

It never seemed to matter much that Daniel Dubois (22-2, 21 KOs) entered the fight as the defending champion or the fact that the 27-year-old native of London brought a 95% knockout rate to pair with his 6-foot-5 frame and two consecutive knockouts of his own since December.

LONDON -- Daniel Dubois retained the IBF heavyweight title by knocking out former two-time world champion Anthony Joshua in the fifth round in a dominant first defense of his belt on Saturday.
