On Saturday night, Manny Pacquiao is set to fight Brandon Rios in Macau. And from the looks of things, their battle is going to be intense, to say the least.

Earlier today, Rios and his entourage were training inside the gym at The Venetian casino in Macau—the gym that both Rios and Pacquiao are using this week in preparation for their fight—when Pacquiao's trainer Freddie Roach entered and told Rios' entourage that their time in the gym was up. Obviously, that didn't sit well with Rios' camp and, within just seconds of Roach entering the gym, an altercation between the two sides took place. Multiple F-bombs were dropped, a whole lot of shit-talking ensued, and the incident ended with Alex Ariza, a member of Rios' camp, kicking Roach in the chest. It was a pretty wild scene.

You can check out the entire incident in the clip above. Just make sure you plug your headphones in before you do.

Is it Saturday night yet?
