Conor McGregor and Khabib Nurmagomedov have been suspended indefinitely pending the investigation into their UFC 229 brawl.
The Nevada State Athletic Commission (NSAC) met to decide whether the fighters should be allowed to compete in the interim but judged that they are both to remain inactive.
The suspensions come after Khabib jumped over the cage following his submission victory over McGregor in round four of their lightweight championship bout in Las Vegas earlier this month.
He started a fight with the Irishman's teammate Dillon Danis, a scrap that triggered a melee, leading the NSAC to withhold his NZ$306million fight purse.
The Commission voted to allow the Dagestani wrestler NZ$153m of that money in the meeting earlier this week.
