The former world heavyweight champion was outworked for much of his 12-round fight against Jarrell Miller in August 2024.

Although Miller (28-1-2, 22 KOs) out-landed his man 183-113, Ruiz (35-2-1, 22 KOs) managed to walk out of BMO Arena in Los Angeles with a majority decision draw on the undercard of Terence Crawford-Israil Madrimov.

Both fighters have since gone their seperate ways, with Miller's handlers are attempting to get him a heavyweight title shot against WBA champion Murat Gassiev. Ruiz, meanwhile, takes on Damian Knyba September 4 at Prudential Center in Newark, New Jersey, live on DAZN.

Ruiz, however, would love to face Miller again one day.

“If he wants to run it back, of course I would run it back,” Ruiz told Ring’s CEO Rick Reeno on the Mr. Verzace Podcast. “That’s a redemption fight. He didn’t get me at my best but I got him at his best. He was in the best shape of his life. I was bigger, but right now, I feel like I can beat anybody.”

Ruiz, 36, doesn’t believe he’s making excuses. The former unified champion underwent immediate surgery for a fractured right hand shortly after his bout against Miller.

That injury, which he says occurred in the fifth round, prevented him from using his full offensive arsenal.

“That was the hardest fight I ever had in my life,” Ruiz continued. “I had to get surgery. There were times that I wanted to quit. I fought through it man, that’s what us warriors do. It could’ve gone either way, I could’ve lost, I could’ve won but it was a draw. I was really blessed that it was a draw. If my hand wasn’t messed up, I would’ve won that fight easily.”
