Tony Bellew has revealed he broke his right hand in the second round of his a surprise victory over David Haye in his first professional heavyweight bout.
Former WBA heavyweight king Haye started positively at the O2 Arena in London but eventually fell away as Bellew took charge and claimed the win with an 11th-round stoppage.
Haye is said to have been suffering the effects of an Achilles injury as the bout wore on, but the WBC cruiserweight champion was carrying a problem of his own after their opening exchanges.
"I broke my right hand in the second or third round," Bellew told BBC Radio 5 Live
"It's sore now but I don't feel the pain - all I think about is winning."
Last message is just say thank you to @mrdavidhaye and hope he is fit and well and goes home safe! Great fight champ your a great fighter!-- Tony Bellew (@TonyBellew) March 5, 2017
Despite that, Bellew took confidence from Haye's deteriorating condition.
"I did it in the second round. It's damaged and it's swollen," Bellew said of his hand in an interview with Sky Sports.
"I hit him with a hard right hand to the body in the first round, two straight into the solar plexus.
"After I hit him there with two of them, I could see with every round that passed, it was like a minute passed from his body to my body and I could see him physically deteriorating round by round and I knew it was going to come."
