MGM Grand, Las Vegas - The co-main event saw former heavyweight champion Charles Martin (28-2-1, 25 KOs) score a one-punch knockout over Gerald “El Gallo Negro” Washington (20-4-1, 13 KOs) in the sixth-round of their showdown.

"I knew that I had him hurt a few times in the fight,” said Martin. “Every round I think I hurt him, but I just couldn't finish him. I knew that I had to take my time in there. It took me some rounds to catch up with him, because he's very quick on the retreat.”

Martin landed a powerful left cross late in the round to send Washington to the mat, eventually forcing referee Tony Weeks to wave off the bout 1:57 into the round. The victory is Martin’s third-straight since the beginning of 2019.

"The referee did what he thought was right,” said Washington. “He's a top notch ref so I won't complain about the stoppage. He put me down and I got up, so I definitely wanted to get back to it."

Martin believes that he answered a lot of critics, and questions in his own head, with this victory.

"This win means a lot,” said Martin. “It shows that I've been working hard. The people can see it. I was never hurt at any point. This has just given me more confidence in myself. I can take the punches and give the punches."
