Ion Cutelaba came in fast and furious during his staredown with Dustin Jacoby on Friday ahead of UFC Fight Night.
The light heavyweight grabbed his opponent by the neck, forcing UFC president Dana White to separate the fighters.
Here's another angle of the incident:
This incident comes two weeks after Jeremy Stephens shoved Drakkar Klose during their weigh-in faceoff. Klose suffered a concussion and cervical sprain of the neck and withdrew from the fight.
White blamed UFC matchmaker Sean Shelby, who was in charge of the staredowns that day, for not getting between Stephens and Klose before the push occurred.
Cutelaba and Jacoby are set to clash on the main card of Saturday's event, which takes place at the UFC Apex in Las Vegas and will be headlined by a pivotal 205-pound contest between former title challenger Dominick Reyes and Jiri Prochazka.
