Petr Yan recently congratulated Khamzat Chimaev on becoming the UFC middleweight champion, but also sparked controversy by questioning Chimaev's Russian nationality.
What happened?
Chimaev, who fights under the United Arab Emirates flag, was hurt by Yan's comments, which he felt were unfair given their personal relationship.
Chimaev has built a gym in Russia and helps the youth there, which he believes demonstrates his commitment to the country.
Why it matters for Petr Yan
Yan's comments have led to a public feud with Chimaev, which may distract him from his upcoming title fight at UFC 323 on December 6.
Yan is set to face Merab Dvalishvili in a bantamweight title rematch, after Dvalishvili dominated their previous fight in March 2023.
What comes next?
Dana White has confirmed that Yan vs Dvalishvili will headline UFC 323, with Alexandre Pantoja and Joshua Van clashing for flyweight gold in the co-main event.
Yan will look to bounce back from his previous loss to Dvalishvili, who set a takedown record en route to a dominant decision win.
Petr Yan's focus will be on regaining the bantamweight title, but the controversy surrounding his comments on Chimaev's nationality may linger, adding an extra layer of pressure to his upcoming fight.
Khamzat Chimaev has made it clear that he is proud to be Russian, despite fighting under the UAE flag, and Yan's comments have only strengthened his resolve to represent his country, he claimed.
The feud between Yan and Chimaev may continue to simmer in the background, but for now, Yan's attention will be on preparing for his title fight against Dvalishvili, scheduled for December 6, at UFC 323.
