Arslanbek Makhmudov explained that he did not realise he had broken his hand against Agit Kabayel.
The two heavyweights met in the ring in December, in Riyadh, as they both put their undefeated records on the line.
Kabayel dropped Makhmudov three times before the clash was waved away in the fourth round, and speaking to Sky Sports, the 35-year-old revealed the extent of his injury, and how it affected him.
"I didn't realise it had happened," Makhmudov said. "I broke it in two places, but I didn't feel pain.
"During the fight, I understand I cannot punch - I want to punch, but my right says 'no'. I tried, tried and tried, but it just wasn't working.
"Even after the fight, I took off the gloves and saw my hand was swollen, and I saw the X-ray where there were two fractures.
"They said 'you don't feel any pain?', I said 'no', and they said to me 'you should cry now because you've had the bone move!' - but I didn't feel anything."
Makhmudov’s next fight is this Saturday against Guido Vianello, live on ESPN+ in the US.
