The American was knocked down on three occasions in a fight of the year contender. The bout was waved off immediately by referee Russell Mora after Wilder was heavily floored for a third and final time in the 11th round.
The 35-year-old will not be kept overnight, however, with his manager Shelly Finkel insisting Wilder 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.’
