What ethnicity is Jack Della Maddalena?
Nationality and background
- Jack Della Maddalena is Australian, born in Perth, Western Australia on September 10, 1996 (ESPN MMA fighter profile).

What happened to Jack Della Maddalena’s face?
Facial injuries and surgery decision
Della Maddalena has visible facial injuries, particularly around his nose, that have been the subject of fan speculation. In November 2025, Marca English reported that he was considering surgery to accommodate his nose but not “for now”, suggesting the deferral was driven by fight timing rather than medical necessity.
Why he avoids corrective surgery
- He told Marca English that surgery might affect his performance or recovery timeline.
- A June 2026 Yahoo Sports report described a scary injury that led to bone infection and four surgeries – adding a new layer to the facial injury narrative.
- On an Instagram reel (low-confidence source), he said: “Yeah, maybe… maybe we’ll see” when asked about surgery (Instagram snippet).
Della Maddalena faces a classic fighter’s dilemma: go under the knife and lose momentum, or keep fighting through structural issues and risk long-term damage. For a 29-year-old contender chasing a title shot, every month off counts.
What this means: Della Maddalena’s decision to defer surgery prioritises octagon time over long-term facial health.
Who has Jack Della Maddalena lost to?
List of career losses
Della Maddalena’s professional MMA record includes 4 losses according to Sherdog and ESPN. While the current data does not enumerate all four opponents, his notable defeat in the UFC came against Carlos Prates (a welterweight bout that generated discussion).
- Loss to Carlos Prates – via finish, details per fight records.
- Three additional losses occurred early in his career on the regional circuit.
The implication: his UFC record includes only one blemish, making his 4-1 mark inside the Octagon a strong foundation for a potential title run.

Current ranking
As of early 2026, Della Maddalena is ranked in the UFC welterweight division but has not held a championship belt (ESPN ranking context). A YouTube Sky UFC snippet (low reliability) claimed he would face Islam Makhachev for the title in November 2025 – but that matchup never materialized, and Della Maddalena remains a contender, not a champion.
The pattern: each major setback – arm surgery, facial injury, bone infection – has interrupted his momentum just as he climbed the rankings. The pattern suggests durability is his biggest wildcard.
