Khabib Nurmagomedov says he will never grace the UFC's Octagon as a fighter again, but he'll be just outside of it on Saturday to corner his teammate and friend from Dagestan, lightweight Islam Makhachev.

Makhachev (19-1) will be in his first UFC main event this weekend in Las Vegas, when he faces Thiago Moises (15-4) as a massive betting favorite (-650).
