Andy Ruiz Jr insists he was not hurt when Anthony Joshua sent him to the canvas in their fight earlier this year.
Ruiz shocked the boxing world to beat AJ at Madison Square Garden and take his three world titles.
The British boxer had knocked down the Mexican-American in the third round but he got up to win by the seventh round.
Joshua has previously claimed he lost to a ‘lucky punch – a punch sent by the gods’.
Ruiz has hit back at those comments and told Sky Sports: “That was a lucky shot for him, too.
“I got lazy. It was a punch in the blink of an eye. I thought: ‘what just happened?’
“I wasn’t that hurt because I wasn’t wobbling. I still had the will and the fire inside of me. I wanted to keep fighting and win the fight.
“Once he dropped me, then got me with a really good right hand, I could eat his punches. Mentally he thought: ‘this guy isn’t going down, what is happening?’
“I had to do everything possible to change the fight, and that’s what I did with the left hook.

“The left hook was a really great shot in the temple. The other times I hit him in the head, he loosened up and got wobbly. I was the better fighter that day because I pressured him, threw more punches and the body shots put him down.”
Preparations are ramping up for their much anticipated rematch on December 7 in Saudi Arabia.
