Magomed Ankalaev’s new opponent is Bogdan Guskov. The UFC confirmed the switch on Monday after Khalil Rountree Jr. withdrew from their July 25 main event due to injury. This change reshapes a fight that already carried real weight for the light heavyweight division.
Why Rountree Jr. Pulled Out
Rountree Jr. withdrew less than two weeks before fight night. The UFC has not disclosed the exact injury. Ankalaev confirmed the news himself on social media, wishing Rountree a fast recovery and confirming he would still fight on July 25 as planned.
This kind of late change usually forces a promotion to scramble. In this case, the UFC had a ready-made replacement sitting one fight away. That detail matters more than most coverage of this switch has mentioned so far.
Why Guskov Was Already Fight Ready
Guskov was not sitting cold when this opportunity came. He was already booked for a rematch against Jan Blachowicz at UFC Belgrade on August 1. That fight had been postponed twice already, once from UFC 328 due to a Blachowicz injury.
This means Guskov spent recent months training for a five-round fight against elite competition. Most short-notice replacements step in undertrained and underprepared. Guskov steps in sharp, which changes how this matchup should actually be read heading into fight week.
The Case For Guskov As A Live Threat
Guskov holds an 18 and 1 professional record with a 1 draw, and he finishes almost everyone he fights. He has recorded 18 finishes in 18 wins, including 15 knockouts and three submissions. Thirteen of those finishes came in the first round alone.
That finishing rate is not a small sample size fluke. Guskov ended a four-fight win streak with stoppages over Nikita Krylov and Ryan Spann before drawing with Blachowicz. He carries genuine knockout power into every appearance, and Ankalaev knows that better than any analyst covering this fight.
What This Means For Ankalaev
Ankalaev lost his light heavyweight title to Alex Pereira in just 80 seconds last October. That loss marked only the second defeat of his entire professional career. He has not fought since, and this Guskov fight is his first chance to answer that loss directly.
The division around him has shifted fast. Pereira vacated the belt to move up and fight at heavyweight. Carlos Ulberg won the vacant title, then suffered a torn ACL that will keep him out for an extended stretch. Ankalaev is fighting into a title picture with no healthy champion standing in front of him.
Why This Fight Matters More Than A Typical Replacement Bout
A win over Guskov keeps Ankalaev in position for the next shot once Ulberg heals. A loss changes that picture entirely and hands Guskov instant relevance in a division that suddenly lacks a clear number one contender. Few short-notice fights carry this much weight on both sides.
Blachowicz, for his part, said the UFC actually offered him this fight first. He said weight concerns on short notice cost him the opportunity, and Guskov’s deal was already locked in by the time he confirmed he could make 205 pounds.

The Bottom Line
Magomed Ankalaev’s new opponent is not a desperate, underprepared replacement. Guskov arrives already sharp from a canceled title eliminator of his own, and his finishing rate makes this a live threat, not a formality. Ankalaev still holds the experience edge, but this fight carries more danger than the original Rountree matchup did.
