In the final press conference before their much anticipated fight, Ryan Garcia was seen getting into it with someone in the crowd rather than with his opponent, Devin Haney.

Garcia went on an expletive-laden rant with mothers and dogs and body parts all mentioned as another chapter in the buildup to the troubled boxer's bout.

After a member of the crowd started chirping at Garcia, he started getting into it with the audience member: 'Hey, where's your mama at, baby? Where's your mama? Oh, I'm going to go flirt with your mama. She about to be fine as f**k. 

The back-and-forth exchange continued: 'Yeah, I want some of your mama. I want your mama now. Hey, your mama probably in my DMs.'

The audience member then brought up Garcia's mother as well - which appeared to take a while to register with Garcia before he retorted.

'F**k you, motherf**ker. No talk on my mama before I f**k you up. 

'Yeah, that fear coming in your mouth like a b***h, dog. I put my d**k in your mouth, b***h. Hey, pause. No Diddy.'

After calm was restored, a stunned Haney simply remarked, 'Something is wrong with this motherf**ker.'

Fans of Garcia's have shown concern for his mental state multiple times as the boxer has made a series of bizarre posts on social media in the build up to this fight.

In recent days Garcia has proposed to Australian porn star Savannah Bond, has accused Haney of a hate crime while identifying himself as a woman, and was kicked out of a New York Mets game before he even threw out a planned first pitch. 

Now, he's set to step in a ring with Haney this Saturday in a fight at the Barclays Center in Brooklyn.
