In the hour leading up to yesterday’s UFC 189 weigh-ins in Las Vegas, Conor McGregor and Urijah Faber were caught on camera backstage getting into a minor physical altercation.

It appears to start as McGregor and Faber cross paths in a hallway behind the scenes at the arena. The footage starts with McGregor patting Faber on the head and calling him, “little man.”

McGregor starts to walk towards a nearby door, while Faber lightly holds him around the waist, laughing while asking, “hey, are you going to be alright?”, presumably in reference to the Irish fighters drawn-out appearance prior to the weigh-ins.

McGregor doesn’t take kindly to that and suddenly he looks to arm drag his fellow fighter and go for a double, but Faber counters and pushes him up against a nearby wall. McGregor pushes back and the break apart with ‘The Notorious’ saying, “get your hands off me or I’ll break your nose,” while Faber protests, “hey, I didn’t touch you.”

McGregor then quickly heads off through a nearby door while Faber walks off looking a little bemused by what just happened, but then turns back and smiles at the camera.

When asked about the incident after the weigh-ins McGregor said that, “It was nothing,” though he appeared to see the tussle in his favor, claiming that, “I arm dragged him into a double – I could have thrown him on his head right there and then.”

Naturally, Faber saw things differently, and wrote on Instagram, “Looks [like] Connor’s Jr high level wrestling hasn’t learned the drag re-drag drill yet. I’ve seen crack heads roaming the streets that look healthier than McGregor right now.”

Overall there wasn’t a whole lot in it, just some minor mind games between the two that boiled over just for a moment, thankfully without any real damage being done that would have landed them in trouble or jeopardize tonight’s fight in which McGregor goes up against Faber’s friend and teammate, Chad Mendes.
