Working with Diaz again signals that Tszyu plans to maintain a partnership that began after fights with Fundora interrupted his run near the top of the 154-pound division. The Australian had already gained momentum with wins over Tony Harrison, Brian Mendoza and Carlos Ocampo before two demanding fights against Fundora halted that progress.
Tszyu returned to winning form in December, defeating previously undefeated Anthony Velazquez by unanimous decision. This performance provided a necessary step forward after setbacks and allowed the 31-year-old to begin rebuilding his position among the division’s top contenders.
“I feel better than ever and I’m ready to get back to work,” Tszyu said, discussing the upcoming fight. “Denis Nurja is undefeated for a reason and is a real challenge. He has a substantial amateur pedigree with eight national titles and has fought at the world championships, so he has fought some sedate fighters there.”
The April competition will be Tszyu’s first appearance in Wollongong, an Australian coastal city with a powerful following for martial arts. Fighting at home again allows Tszyu (26-3, 18 KO) to further regain momentum in familiar surroundings and return to the title conversation.
Nurja (20-0, 9 KO) remains undefeated and sees this fight as the biggest opportunity of his career. The 31-year-old Albanian has been competing professionally since 2018 and has fought in several countries, gradually rising through the rankings. He recorded three victories in 2025 and began his 2026 campaign in February with a first-round stoppage of Jose Gregorio Marcano.
“There’s a reason I’m 20-0, and I didn’t build that record by playing it unthreatening,” Nurja said. “It’s the biggest opportunity of my career and I’m ready for it. People talk about Tim coming back, but I’m the one standing in front of him.”
The event will also feature a 12-round IBF super bantamweight title eliminator between Australian challenger Sam Goodman (21-1, 8 KO) and Argentine Rodrigo Ruiz (23-1, 17 KO), as well as a middleweight fight between undefeated 2024 Australian Olympian Callum Peters (5-0, 5 KO) and Delio Mouzinho (4-0, 4). KO).
The event will stream on Prime Video starting at 9 p.m. ET/6 p.m. PT for Prime members in the U.S. and select international markets.
Tszyu had regained his momentum earlier in his climb up the division. Another victory will bring him back to the world title fights that were once within his reach.
