This will be very head shaking for Petr Yan. We cannot be quite certain if Khabib, Henry Cejudo or the others that Petr Yan asked to be in his corner would agree. It also appears that the only fighter who agreed to be in his corner is Suga Sean O'Malley. There were other news articles that were mentioning that Petr Yan ignored Khabib.
However, it seems that Yan will be heading to the Vystar Veterans Memorial Arena in Florida without his coaches and cornerman. On Tuesday, MMA reporter Bruno Massami broke the news that entry into the United States has been denied for the coaches that were set to corner him in his championship bout.
This major setback for the 29-year-old is another instance of the hard stances that governments around the world have taken against Russia following its invasion of Ukraine three weeks ago. Along with economic sanctions levied on the Russian government and the country’s oligarchs, sports leagues have pulled events from the country, and Visa requests for Russian athletes have been denied in a various nations.

Such coach/team fluctuations and training camp changes so close to the fight are never a good sign. Granted, Aljo shouldn't be an issue for Yan even with those issues, but it definitely doesn't help. If these types of issues continue it could pass a serious issue when faced with a more dangerous opponent. There is definitely something to a lot of Dagestani fighters coming to the US for longer periods (mostly AKA), and I am sure that Yan would benefit from such a move.
