Kell Brook had to be taken to the hospital for a broken eye socket, after his defeat to Gennady Golovkin.
Dominic Ingle threw in the towel in the fifth round of the O2 Arena bout, after seeing his boxer had severe visual impairment.
The British boxer would have gone on for longer, and insists he is eager to get back in the ring.
Brook moved up two weight divisions to face Golovkin and even though he called for a fight of the winner of Saul Canelo Alvarez v Liam Smith, he admits that he may now be better suited to light middleweight in his next fight, despite having an IBF title to defend at welterweight.
“In the second round, he broke my eye socket but I was tricking him, I was frustrating him. I was starting to settle into it but when you see three, four, five of them, it’s difficult,” said Brook.
“I’d be most suited at light-middle. I know (Liam) Smith and ‘Canelo’ (Saul Alvarez) are fighting next week: I would love the winner.
“He’s a scary champion but I would fight him again. I’m trying to give back to the fans and I hope they enjoyed the fight while it lasted.
“It wasn’t my night because there was much more to come from me but I was seeing five of them out there.
“I’m a warrior, I want to carry on, I was ready to fight on. Anyone who trains with me knows that.
“I was starting to come on. We knew the first five or six rounds would be tough, but you would have to talk to my coach to ask him why he pulled me out. I’ll be back.”
