Ankalaev Returns Against Guskov as Rountree Injury Reshapes Abu Dhabi

Magomed Ankalaev walks back into the cage Saturday at Etihad Arena for the first time since October, and the man across from him isn't the one he trained for. Khalil Rountree Jr., the No. 5 light heavyweight, pulled out with an injury inside the final fortnight, and No. 9 Bogdan Guskov took the main event of UFC Fight Night: Ankalaev vs. Guskov on under two weeks' notice.

That's a significant shift on paper. Ankalaev, ranked No. 1 at 205, carries a 21-2-1 record into the July 25 headliner, while Guskov steps up at 18-3-1. The short-notice angle matters, but so does the punching power: Guskov owns 15 knockouts across those 18 wins, a finish rate that makes him a live dog even on a fraction of a full camp.

From Champ to Challenger

The backdrop here is Ankalaev's title loss. He surrendered the belt to Alex Pereira last October by first-round TKO, stopped on elbows in a result that flipped the division's storyline overnight. Before that night, Ankalaev hadn't lost in years and built his case on control, pressure and a grinding style that few could solve.

So this is a reset fight. A former champ needs to look like a former champ again, and a soft landing isn't really on offer against a guy who hits as hard as Guskov does. The trap for Ankalaev is obvious: treat a short-notice replacement as a formality and get caught by a fighter with nothing to lose and one big weapon.

Guskov's own recent form is worth a longer look. His last outing ended in a third-round draw against Jan Blachowicz, a result that kept him in the rankings mix without cementing anything. Now he inherits a main event that could vault him up the ladder if he lands clean, and drops him nowhere if he doesn't. That's the math of taking a fight like this.

The Blueprint and the Broadcast

Ankalaev's blueprint should be about neutralizing the danger. His 11 knockouts suggest power, but his identity has always leaned on wrestling and top control rather than trading. Against a heavy-handed opponent working off a rushed camp, minutes spent on the mat are minutes Guskov's power can't do damage.

The card also runs on an unusual clock for US and UK viewers. Prelims kick off at 9am ET/6am PT, with the main card following at 12pm ET/9am PT, streaming on Paramount+ in the States. It's a daytime watch built around Abu Dhabi's local schedule, which tends to sap some of the atmosphere but doesn't change the stakes.

For the division, the ripple effects sit at the top. Pereira, now ranked No. 3 after his title run, is 13-3 with 11 knockouts and lining up a title eliminator against a to-be-announced opponent. Ankalaev remaining the No. 1 contender only makes sense if he wins convincingly here, so a stumble against a replacement would scramble the queue.

Stakes for Both Men

Rountree's absence is its own subplot. The No. 5 light heavyweight is 15-7 and coming off a third-round TKO loss to Jiri Prochazka, so he needed this fight to steady his standing. Sitting out a headliner he was booked for keeps him in a holding pattern he'd rather escape.

What should come next depends entirely on how decisive Saturday looks. A clean Ankalaev win puts him right back in the conversation for another crack at the belt, ideally with a rematch against Pereira dangling as the marquee option. Anything less than dominant, and the case gets harder to argue.

For Guskov, the upside is enormous relative to the risk. Beat the No. 1 contender on short notice and he's suddenly a genuine top-five name with a signature win, not a stopgap. Lose competitively and he keeps his ranking and his reputation as a guy who shows up when called.

Official judges' scorecards will follow each bout once the results are in, but the headline question is simple. Can Ankalaev, stripped of his belt and out of the cage since last fall, remind everyone why he sat at the top of the division for so long — or does a short-notice puncher throw the whole picture into chaos?
