Devin Haney's father and trainer Bill watched on last weekend as his son was beaten for the first time in his professional career by Ryan Garcia, being dropped three times in the process.

Prior to the bout, Haney Sr had made some remarks suggesting that a sparring session with Devin is what prompted Mayweather to retire - adding that boxing was now in the 'Devin Haney era.
These remarks seemingly didn't go down to well with Mayweather, and the pair met in a heated lengthy argument on Instagram live as a result.
The pair first came to blows over the sparring stories.
Mayweather got angry and shouted: "Congratulations on you having an undefeated fighter in the gym.

"But I am undefeated under the lights. Is your fighter undefeated under the lights?"
The argument then developed with Haney Sr criticising the former 15-belt world champion's undefeated professional record of 50 wins with no defeats.
He shouted: "You’re a bulls***-ass n***a... F*** your 50-0, that s*** don’t mean nothing.
"Look at the opponents you picked, it means nothing."

Mayweather responded: "Bill, Bill, Bill. I don't have to have a p***ing contest with you. You know why?
"Bill you know I have always had respect for you. I just called to find out what your problem is with me."

The feud continued with Haney moving on to take aim at his new rival for the handling of his children, as the argument became personal.
Finally, Haney insisted he would continue to work with his WBC super-lightweight champion son, to which Mayweather responded: "You need some help? He needed help the other night."
The famous father hit back: "You know what time it is with me when I see you.
"The Haney business will be continuing, have I ever needed your help with anything?
"Your son needs help tonight not the other night, you bald a** hurt man.
"My son needs me, tomorrow today and every day. We don't need you for dog s***."
