Watch: Relive Khabib Nurmagomedov's epic lightweight title fight against Al Iaquinta at UFC 223

On April 7th in 2018, Khabib Nurmagomedov claimed the UFC lightweight title at UFC 223. The Dagestani fighter had to deal with bizarre circumstances leading up to the title match - from the last-minute change of opponents to Conor McGregor throwing a dolly at Nurmagomedov's bus.

Khabib Nurmagomedov was originally expected to face Tony Ferguson at UFC 223. The fight was supposed to be for the undisputed belt as Conor McGregor had been stripped of his lightweight crown. The promotion did this due to the Irishman's inactivity in the Octagon.

But as luck would have it, Tony Ferguson had to pull out from the UFC 223 main event as 'El Cucuy' damaged his knee while training. The promotion decided to rope in then-featherweight champion Max Holloway to replace Ferguson.

The short-notice appointment made the matchup even more exciting as Holloway had the opportunity to become the second two-weight champion in the UFC.

However, a day prior to the match, another setback hindered Khabib Nurmagomedov's title shot as the New York Commission deemed the Hawaiian medically unfit to fight. 'The Eagle' was left without an opponent just 24 hours before the event.

Paul Felder vouched to save the day but the NYSAC rejected his appeal as he was unranked. So, the UFC decided to enlist Al Iaquinta for the main event, who was Felder's original opponent for UFC 218. The Brooklyn native stepped on the scales slightly above the weight limit but the UFC greenlighted the event nevertheless.

Khabib Nurmagomedov's grappling ability was on full display in the main event of UFC 223 and dominated Al Iaquinta to win the fight via unanimous decision.
