Prates Breaks Down Della Maddalena Round By Round
Round 1 was competitive. Della Maddalena pressed forward, worked his jab, and mixed in body shots while Prates circled and attacked the leg. Prates landed clean punches, knees, and a heavy leg kick, but Della Maddalena scored a late takedown before the horn.
Round 2 was where the damage started adding up. Prates landed knees, a head kick, sharp jabs, and calf kicks that clearly bothered Della Maddalena’s lead leg. Della Maddalena still fired back and found moments with his hands, but Prates was landing the harder, cleaner strikes by the end of the round.

Round 3 ended the fight. Della Maddalena switched stances to protect his damaged leg, but Prates kept attacking. He hurt Della Maddalena with knees, elbows, and calf kicks, then dropped him and followed with ground strikes until the referee stopped it.

After the win, Prates brought his mother and daughter into the cage and called for the next title shot.
“I come for war,” Prates said. “I train so much. I make everybody travel so far, so I couldn’t come here and just lose.”
“I respect Jack, he’s a great champ but it’s just business,” Prates said. “It’s part of the game. Jack is a great champ. I need to ask something? Who is next? In August, I will be first in line watching [Islam] Makhachev and Ian [Machado Garry] and I will be next. I’m going to fight the winner.”
For Della Maddalena, this is a hard reset after the Makhachev loss. For Prates, it is the biggest win of his career and a clean argument for a title eliminator, if not the next shot outright. If Makhachev and Ian Machado Garry are next for the belt, Prates just made sure his name is stuck in the same conversation.
