UFC Abu Dhabi loses headliner to injury, sets new light heavyweight pairing

UFC Abu Dhabi will move its light heavyweight center to accommodate an injury to Khalil Rountree Jr., according to Yahoo Sports. The July 25 event, set for Etihad Arena, was originally expected to feature Rountree in the main slot against former UFC light heavyweight champion Magomed Ankalaev, but Rountree has been ruled out and the promotion is turning to a replacement option to keep the headline fight intact.

The replacement fighter is listed as Bogdan Guskov in the report, with the key detail being that Guskov will take Rountree’s place to face Ankalaev. A second name also appears in the same Yahoo summary, “Bogdan Buskov,” described as a rising contender who would replace Rountree. Because the report does not clarify the discrepancy in the preview text, fans should treat the spelling as a confirmation to watch for on UFC’s official listings in the coming days.

Ankalaev’s role in the matchup is clear in the reporting. He is positioned as the former UFC light heavyweight champion and will remain the opponent in the headliner framework, meaning UFC is effectively preserving Ankalaev’s opportunity for a marquee bout on the Abu Dhabi card even after the scheduled opponent change.

For the light heavyweight division, replacement fights at the top of the card can materially shift the competitive picture. Ankalaev’s position as a past champion typically puts him in the mix of the division’s high-leverage matchups, and a short-notice swap changes how contenders build momentum. Even when the matchup holds, the new opponent profile can affect stylistic matchups, preparation time, and how quickly the winner can move into the next title-relevant discussion.

Rountree’s absence is the central complication. The report attributes the change to an injury that prevents him from competing on July 25. While injuries are not uncommon in MMA, a headliner withdrawal forces the promotion to balance urgency with a credible challenger who can make weight, complete medical and pre-fight requirements, and arrive ready enough to keep the event’s stakes from collapsing.

Guskov stepping in, if confirmed as written, would offer an additional high-stakes opportunity for the incoming fighter. The Yahoo report frames the replacement as a “rising contender,” which implies UFC is aiming to keep the main event matchup competitive rather than simply filling a slot. For Ankalaev, that means the bout still presents an opponent the promotion views as legitimate enough to anchor a top-billing fight.

Going forward, the immediate thing to watch is UFC’s official fight card update for UFC Abu Dhabi, including the confirmed replacement name, the final pairing, and any downstream changes that follow when a headliner is altered. The event still matters for the light heavyweight title picture, but how the division’s hierarchy shifts will depend on who actually steps in and how the replacement bout unfolds once both fighters are officially listed.

Ultimately, UFC Abu Dhabi will still deliver a headline light heavyweight matchup featuring Ankalaev, but the road to the ring has changed. Rountree’s injury has forced the promotion into a late adjustment, and UFC will be judged by whether the replacement provides the kind of credible, fight-night-ready challenge fans expected from a main event.
