Jack Della Maddalena (18-3) signed with the UFC in September 2021 following a decision win over Ange Loosa on a Dana White’s Contender Series card. Before the bout, UFC matchmaker Sean Shelby said of Della Maddalena, “I thinkDella Maddalena is probably the best prospect out of New Zealand or Australia at welterweight. He’s a big guy. He throws a ton of offense, and he’s really good in the clinch. The win over Loosa marked the first time Della Maddalena had won a fight via decision. He went into the bout on a run of nine stoppages (eight knockouts, one submission) after opening his professional career at 0-2 with two stoppage setbacks. Della Maddalena was the reigning and defending Eternal MMA welterweight titleholder heading into the DWCS card.
The Australian scrapper opened his official UFC run with four first-round stoppage wins and three “Performance of the Night” bonuses. He finished Pete Rodriguez, Ramazan Emeev, and Danny Roberts by knockout before stopping Randy Brown via submission.
In his first fight to go the distance under the UFC banner, Della Maddalena was in a “Fight of the Night” bonus-winning affair with Bassil Hafez, which Della Maddalena won via split decision. He followed that with another split decision, topping Kevin Holland in September 2023.
Della Maddalena followed his victory over Holland with a third-round knockout triumph over former UFC welterweight title challenger Gilbert Burns in March 2024.
Della Maddalena claimed the UFC welterweight title in May 2025, defeating then-champion Belal Muhammad by unanimous decision at UFC 315.
He lost that title to Makhachev in November.
Over the course of his nine-fight UFC career, Della Maddalena has picked up six fight-night bonus awards. He is the No. 1 fighter in the official UFC welterweight rankings.

Carlos Prates (23-7) joined the UFC in 2023 with a knockout win on a Dana White’s Contender Series card. Since then, the 31-year-old has gone 4-0 with the UFC, winning each of those fights by knockout. Prates also earned performance bonuses for each of his four knockouts. In his most recent outings, Prates scored an August 2024 stoppage of Li Jingliang before moving on to defeat Neal Magny via TKO on a UFC Fight Night Card in November.
Prates was on an 11-fight winning streak until he met Ian Machado Gary in April 2025, losing that contest via decision.
Since that setback, Prates has scored back-to-back knockout wins, stopping Geoff Neal in the first round in August 2025 and then halting former UFC welterweight champion Leon Edwards in the second stanza in November.
Prates, the No. 5 ranked UFC welterweight has picked up six “Performance of the Night” bonuses during his seven-fight UFC run.
