Errol Spence Jr. offered himself to take over from Jermall Charlo on Tim Tszyu's July 25 welterweight card in Australia after Charlo's visa trouble . Spence called out Charlo's public trash talk, stating the opponent 'talks a lot of s*** '. The visa denial killed the scheduled bout just days before fight night. Spence's offer leaves Tszyu needing a new opponent on short notice as promoters rush to rebuild the event. The sudden turn has fans weighing in about what comes next for the Australian headline . Spence's history of high-pressure finishes makes his pitch hard to ignore, even on short weeks. Charlo's team has yet to comment on the denial, leaving the picture unclear around his next move. For now, the focus stays on how fast a new deal gets done as the promotion chases a backup plan.
