Deontay Wilder was taken to the hospital after his brutal knockout loss to Tyson Fury in Las Vegas.
In a fight that was a contender for fight of the year, the American was knocked down three times. Referee Russell Mora immediately stopped the fight after Wilder was heavily floored for the third and final time in the 11th round.
Wilder was defeated for the second time in a row by the Brit, who retained his WBC title with the victory, and the American will now undergo precautionary tests in the hospital.
Wilder, 35, will not be kept overnight, according to his manager Shelly Finkel, who claims he is in good health.
Boxing journalist Dan Rafael tweeted: ‘Was texting with Wilder’s manager Shelly Finkel.
‘Said Deontay is OK and won’t be staying overnight at the hospital.’
Wilder himself did speak after the fight, insisting he wasn’t sure what went wrong.
‘I did my best, but it wasn’t good enough tonight,’ he said. ‘I’m not sure what happened. I know that in training he did certain things, and I also knew that he didn’t come in at 277 pounds to be a ballet dancer.
‘He came to lean on me, try to rough me up and he succeeded.’
