Arman Tsarukyan headbutted Dan Hooker as tensions spilled over at the weigh-ins ahead of their UFC Qatar grudge match.
The pair came together for the customary face-off after taking to the ceremonial scales, only for Tsarukyan to instantly lunge his skull into Hooker’s forehead, leading to the hasty separation of the fighters by security and UFC matchmaker Mick Maynard.
