Conor McGregor and Khabib Nurmagomedov have been handed lengthy suspensions by the Nevada State Athletic Commission following their roles in the post-fight melee at UFC 229.
Nurmagomedov has been handed the heavier punishment, having instigated the unsavoury scenes following his win over McGregor, with the Russian receiving a nine-month suspension and a fine of $500,000.
McGregor, meanwhile, has been given a six-month ban and a fine of $50,000. Both suspensions have been backdated to the event on October 6 last year.
Nurmagomedov, whose suspension could be reduced by three months if he takes part in anti-bullying campaign in Nevada, retained his UFC lightweight title at the T-Mobile Arena in Las Vegas when he submitted McGregor in the fourth round.
The 30-year-old threw his gumshield towards McGregor's corner, scaled the octagon before attempting to attack someone in the Irishman's team in the crowd.
While that was happening, McGregor was involved in a confrontation after a couple of members of Nurmagomedov's team had entered the cage.
At the same NSAC hearing, two of Nurmagomedov's training partners - Abubakar Nurmagomedov and Zubaira Tukhugov - were issued one-year suspensions and each fined $25,000.
