Things got rather heated during a press conference between Saul 'Canelo' Alvarez (56-1-2) and Caleb Plant (21-0-0) on Tuesday.
The two will come face-to-face in the four-cornered ring on November 6th in Las Vegas to determine who is the undisputed super middleweight champion.
Both fighters kickstarted the build-up to their much-anticipated fight in Los Angeles on Tuesday and the situation turned very nasty rather quickly.
Canelo was pretty chatty on stage right at the start of the event and words were exchanged between the two fighters before and during the face-to-face meet.
It's still not known what was actually said, but it was enough for Canelo to forcefully shove Plant away from him.
The American returned to the centre of the stage and swung for his adversary, with Canelo producing some Matrix-style moves to dodge the punch.
He then countered with a powerful punch of his own, which has left Plant with a nasty-looking cut under his right eye.

Things did settle down a touch after the brawl seen above, however, the two fighters continued to hurl insults at one another as the press conference progressed.

It's one of the most heated pressers we can remember in recent times and one that makes the fight on November 6th even more of a mouthwatering prospect.
Bring. It. On!
