UFC 331 adds two more heavyweight bouts to Los Angeles card

The UFC has added two new heavyweight fights to UFC 331, an action the promotion announced as it continued to shape a fuller card for its September 19 show Arena in Los Angeles, California. The update increases the number of heavyweight matchups on the docket and indicates the UFC’s continued focus on the division’s depth as the event approaches.

According to the UFC’s official announcement reported Wednesday, the two newly added bouts will be contested in the heavyweight division and slot into the existing schedule for UFC 331. Heavyweight remains a central selling point for UFC PPV events, and additional matchups in that class typically help balance the card when the promotion is still finalizing details across multiple weight divisions.

UFC 331 is positioned as a major fall event, and the incremental additions reflect a common UFC strategy in the final weeks before fight night. Cards at this stage often see late adjustments as camps close out training blocks, broadcast and promotion logistics are confirmed, and matchmaking gaps are filled.

While the event location and date are set, the specific opponent pairings for the added heavyweight bouts are the kind of detail that matter most to fans and to bettors. At this stage, the available information confirms that two heavyweight fights were added, but it does not provide enough verified detail here to name the athletes without risking inaccuracies.

Arena in Los Angeles adds another layer of context for the UFC 331 build. Events in the U.S. market are often used to maximize mainstream reach, and heavyweight fights tend to draw strong attention because of their potential for high-impact finishes, even when the fights are primarily about striking exchanges and grappling control rather than a single knockout moment.

For UFC 331, the bigger story is how the card is taking shape through these late additions. Once the full lineup is confirmed, the next questions will be how the added heavyweight bouts align with the division’s broader matchmaking picture and whether either matchup serves as a stepping-stone toward a future title eliminator.

As fight week approaches, the most useful developments to watch will be the final complete card order, any additional bout announcements that come after Wednesday’s heavyweight additions, and the official release that confirms every pairing. Those items will provide the clarity fans want on the matchup implications for the heavyweight rankings.
