Both sides have agreed to the 145-pound matchup, which was originally supposed to take place on Oct. 18 in Boston, but was postponed due to a Magomedsharipov injury. The UFC Fight Night event will take place at CSKA Arena and air on ESPN+.
It's an unfortunate change of venue for Kattar (20-3), who fights out of Methuen, Massachusetts. Kattar, who is 4-1 in the UFC, had asked for the Magomedsharipov fight specifically, however, and he was willing to forego fighting closer to home to keep it together.
Magomedsharipov (17-1), of Russia, is considered one of the top prospects in the sport. The 28-year-old is 5-0 in the UFC, including a win over veteran Jeremy Stephens in his last outing.
