Saturday's UFC main event was predictable in a way, in that the undefeated champion Khabib Nurmagomedov won. What happened next was not as predictable.
Nurmagomedov (29-0) announced his official retirement from mixed martial arts, following the death of his father Abdulmanap in July. He revealed his mother did not even want him to compete at UFC 254, but he promised her it would be the final bout of his career.
The Dagestani legend retires as arguably the greatest fighter of all time. And he departs a lightweight division that is now full of uncertainty. UFC president Dana White admitted he does not know what he'll do in the aftermath of Nurmagomedov's retirement.
