The UFC returns to Moscow, Russia for UFC Fight Night 163. Originally, a heavyweight fight between Alexander Volkov and Junior dos Santos was scheduled for the main event. However, dos Santos would be forced to pull out of the fight with an injury. This pushed the featherweight co-main event into the new main event slot.
The new main event now features two exciting featherweight prospects as Zabit Magomedsharipov faces Calvin Kattar. Magomedsharipov has now lost a fight since 2013 and will be looking for his 14th straight win against Kattar.
