Errol Spence Jr. and Tim Tszyu are set to meet on Saturday, July 25th at the Afterpay Arena in Sydney, Australia in a 12-round super welterweight showdown between two former world champions. There are no titles on the line, but plenty at stake: Spence returns from a nearly three-year layoff looking to force his way back into the world title picture, while Tszyu is chasing the biggest win of his career on home soil. The fight headlines a PBC Pay-Per-View event on Prime Video.
Errol Spence Jr. is an American boxer out of DeSoto, Texas with a professional record of 28-1 (22 KOs). A former unified welterweight world champion who held the WBC, IBF, and WBA titles, Spence is widely regarded as one of the best pure boxers of his generation. He has not fought since July 2023, when he suffered the first loss of his career, stopped in the ninth round by Terence Crawford in their undisputed welterweight title showdown. Spence steps up to super welterweight for his comeback after almost three years away from the ring.
Tim Tszyu is an Australian professional boxer with a professional record of 27-3 (18 KOs). The former WBO super welterweight world champion and son of Hall of Famer Kostya Tszyu, he lost his title to Sebastian Fundora in 2024 and went through a rough stretch, but has rebuilt with three straight wins, most recently a unanimous decision over Denis Nurja in April 2026.
Spence enters as the favorite, but this is a live dog spot for Tszyu. The questions around Spence’s ring rust after such a long layoff are real, and Tszyu is the busier, fresher fighter with a partisan Sydney crowd behind him. If Spence shows any rust, Tszyu has the pressure and volume to make him pay. It’s a genuine crossroads fight, and both men have every reason to leave it all in the ring.
