Floyd Mayweather went through his entire boxing career without getting floored.
The 42-year-old maintained an unbeaten 50-0 record after beating the likes of Oscar De La Hoya, Ricky Hatton and Manny Pacquiao, picking up 27 wins by KO.
But the former lightweight champ met his match on Monday night at the Monster Energy 50K Charity Challenge.
Mayweather decided to go head to head against the great Larry Williams, a man who earned the nickname "Bone Collector" for his ability to "break ankles."
'Money' soon regretted his life decisions when Williams sent him to the shops at the UCLA Pauley Pavillon in Los Angeles, California.
The crowd went wild as Floyd got dropped by a lethal cross-over stepback three.
It's not everyday you see Floyd Mayweather knocked to the ground, is it?
To add insult to injury, Williams bagged a three pointer as the 42-year-old just sat on the ground and laughed.
As you can imagine, social media were soon to voice their thoughts on the incident.
Mayweather eventually got to his feet and carrie on in good spirits.
I am fully expecting Conor McGregor to throw down a Basketball challenge in the coming hours.
