Andy Ruiz Jr apologised for not training properly for his rematch with Anthony Joshua.
The Mexican-American weighed in three stone heavier than his challenger on Friday and it showed in the ring.
Joshua dominated from start to finish to banish the memories of his defeat by Ruiz in June.
And Ruiz was at pains to insist his performance was down to his lack of effort in training.
“For this fight, I was overweight… I should have trained harder. I should have listened to my coaches more. Maybe I shouldn’t have put on all this weight that I did.
“I trained myself for this fight… I’m sorry to my coach and to my dad.
“I’d like to say the three months of partying didn’t affect me, but it did. … I think the partying and all this stuff got the best of me.
“He was the better man, I should have taken it seriously and it would have been a different fight.
“We’re going to work harder in the gym and get better… I’m going to dedicate myself more.
“I’d love to do it again but in better shape.
“I felt I was going to do my best, you can’t doubt yourself. Once I’m in the ring I have to motivate myself and pray that everything is OK.
“I won one, he won one and I want to do it again.”
Ruiz’s coach Manny Robles sat next to him at the press conference but refused to blame the dethroned champion for his defeat.
“As a coach you have to be with your fighter 100 per cent, even when things aren’t going well,” he said.
“He’s not the only fighter who has situations happen in camp, I’m there for him 100 per cent through good and bad, through thick and thin.
“I have to apologise to him too because this is a team effort and when you don’t win it hurts.
“But you’ve got to stick with your fighter, there are a lot of things people don’t know.”
