Anthony Joshua reportedly was "hurt badly" during a training session with boxer Joey Dawejko prior to his fight against Andy Ruiz Jr. at Madison Square Garden in New York last Saturday, per World Boxing News.
World Boxing News reported Dawejko knocked Joshua down while sparring, which "visibly marked his face."
Joshua's promoter, Eddie Hearn, has denied that the boxer was injured during the sparring session.
"Absolutely there is no truth that he was badly hurt in sparring, there were no health concerns going into the fight," Hearn said, according to Gareth A. Davies of The Telegraph.
Entering the fight undefeated at 22-0, Joshua stepped into the ring as a heavy favorite against Ruiz. However, Ruiz shocked the world by knocking Joshua down multiple times in the seventh round, ultimately winning via TKO:
With that, Ruiz (33-1) became the first heavyweight champion of Mexican descent as he took his opponent's WBA, WBO, IBF and IBO heavyweight titles.
The result of the fight led to boxing star Manny Pacquiao calling it "one of the biggest upsets in boxing history":
Per ESPN's Ariel Helwani, Hearn said on Saturday that there will be a rematch in November or December in the United Kingdom.
