Vito Mielnicki Jnr and Kamil Gardzielik both came in at the same weight, 159.5lbs, on Friday, ahead of their 10-round middleweight bout on Saturday night at Prudential Center in Newark, N.J.

Mielnicki, 20-1-1 (12 KOs), a native of Roseland, New Jersey who now lives and trains in Houston, is appearing at his home arena for the fifth time, as he seeks to make a big impression after having back-to-back fights in which he was not pleased with his performance.

“I’m not happy with my last two performances so I’m gonna use this stage and really showcase my talents and what I’ve been working for since I was a kid. Just translate everything that I’m doing in the gym and put it on the big stage on the television screen,” said the 23-year-old Mielnicki.

Gardzielik, 19-0 (4 KOs), of Warsaw, Poland will be fighting for the first time in the United States. The 32-year-old says he didn’t come to America just for a payday.

“I’m here to show the fans that the level of boxing in Poland is very high. And I came here to win,” said Gardzielik.

While the main event build-up has been marked by muted respectfulness, there’s been nothing muted about the build-up between Lorenzo “Truck” Simpson and Jahi Tucker, who clash in the middleweight co-main event. Simpson, who weighed 159.5lbs, and Tucker, who was 160lbs even, have traded barbs and threats on social media, but maintain that it’s just their competitive spirits shining through.

“It ain’t beef  because where I’m from something would have happened but it’s competitive. He a good fighter; I’m a great fighter. It’s just competitive spirit,” said Simpson, 15-2 (9 KOs), of Baltimore.

“We old school fighters, it’s about respect. It ain’t for a record, we’re both young, we’re gonna have nine more years to compete, it’s about showing who’s better.”

The fights will air live on ESPN+, beginning at 5:30 p.m. ET.
