Jermall Charlo has reportedly been added to the highly anticipated Errol Spence vs Tim Tszyu boxing card, creating major buzz as fight fans look ahead to an international showdown. The update signals that the event, already drawing attention for its top-tier talent, will now include Charlo as well—an announcement that is being treated as breaking news.
According to the posted information, Charlo’s inclusion marks a significant milestone: it will be his Australian debut. That detail matters because it indicates Charlo will be competing in a new market and potentially in front of a different style of crowd and media spotlight compared to his usual venues. For supporters, an Australian debut is also a sign that the promotional reach for the Spence vs Tszyu clash is expanding beyond a single storyline, turning the card into a more prominent “must-watch” event for casual and hardcore audiences alike.
The card is scheduled for July 25 in Australia, and the announcement suggests Charlo’s appearance will be part of the same evening of action. With this kind of lineup, the fight night becomes more than a single main event—it turns into a full slate where additional marquee matchups can raise the stakes and broaden viewership. Charlo’s name carries strong mainstream recognition in boxing, and adding him to a card headlined by a Spence vs Tszyu matchup elevates the overall appeal of the night.
The information comes as a public posting credited to MainEventTV. The post frames Charlo’s addition as an update tied directly to the event promotion, using emphatic language and emojis to emphasize urgency and excitement. That tone reflects how quickly the news is spreading and how important Charlo’s presence is to fans who follow the division.
While the brief text does not specify Charlo’s exact opponent or the division details for his appearance on the card, the key takeaway is clear: the organizers are adding a high-profile fighter to strengthen the card’s star power. In modern boxing, cards are often built around not only the main attraction but also strong undercard content, and Charlo’s addition fits that pattern. His involvement also suggests the event may attract broader global attention, since both Spence and Tszyu are widely followed, and Charlo’s reputation adds another layer of credibility and excitement.
For Tim Tszyu and Errol Spence supporters, the presence of Charlo could also heighten the event’s overall narrative. Major fighters joining each other’s orbit can influence fan interest, shape speculation about future matchups, and create additional storylines that extend beyond the final bell of the main event. Even without opponent information, the mere addition of a fighter of Charlo’s stature can change how people view the night—transforming it from a single headline bout into a larger boxing moment.
From a promotional standpoint, announcing Charlo’s Australian debut alongside Spence vs Tszyu indicates the event is positioned as a major international attraction. July 25 in Australia becomes an even more significant date on the boxing calendar, as the card now features multiple high-level fighters. This can also improve the chances of strong media coverage and audience retention throughout the night, since fans tune in not just for one fight but for several events featuring top names.
Overall, the news is that Jermall Charlo has been added to the Errol Spence vs Tim Tszyu card, with the expectation that he will make his Australian debut on July 25. The announcement credits MainEventTV as the source of the update, and it strongly implies a major, stacked fight night for boxing fans in Australia and around the world. Source: MainEventTV
