Fight Announcement and Logistics
Middleweight contender Vito Mielnicki Jr. will meet recent title challenger Austin “Ammo” Williams on September 4 2025 at Newark’s Prudential Center. DAZN will stream the bout, promoted by Matchroom Boxing.
Background and Recent Trajectories
Mielnicki entered the fight after a six-fight unbeaten run and a new deal with Matchroom. His only blemish, a majority-draw with Connor Coyle, was later changed to a no-contest after Coyle failed a drug test. Williams is rebounding from losses to Hamzah Sheeraz and Carlos Adames, both in 2024 title-level bouts in the United States.
Key Fighters Profile
Mielnicki, 26, from Roseland, New Jersey, debuted at the Prudential Center in 2019. He is 23-1 (13 KOs) and ranked No. 2 by the WBO. Williams, 30, from Milwaukee, fights out of West Palm Beach; he is 20-2 (13 KOs) and ranked No. 11 by the WBO.
Numbers and Rankings
Mielnicki’s 23-1 record includes 13 knockouts; Williams is 20-2 with 13 knockouts. In the WBO, they sit at No. 2 and No. 11 respectively; the IBF and WBC place Mielnicki at No. 7 and Williams at No. 14.
