Just been reading a few interesting Russian articles on this. You'll have to translate the pages obviously. https://www.sport-express.ru/martia...ufc-ne-podpisyvayut-boycov-iz-rossii-1636615/ https://www.sport-express.ru/martia...zhet-pereyti-v-ufc-intervyu-s-boycom-1637147/ https://www.sport-express.ru/martia...lbert-tumenov-s-kem-sleduyuschiy-boy-1635901/ https://www.sport-express.ru/martia...lbert-tumenov-s-kem-sleduyuschiy-boy-1635901/ Basically says that the UFC has a limit on how many Russian fighters it will have on the roster at one time and they're at that limit now and it's basically a one in/one out policy at the moment. - Shlemenko might be an exception as he's already known in the US. - Albert Tumenov, Rustam Kerimov, Magomed Magomedov, Albert Duraev, Zhalgas Zhumaglov, Alexander Shabliy, Timur Valiev and Aliaskhab Khibriev are all actively trying to get into the UFC at the moment, but the UFC might not be able to sign them all. - There's no testing in ACA, so some fighters aren't trying to come over. - UFC doesn't want 4-5 ranked fighters in one division to be Russian, for business reasons.
