Deji may have been stopped by Floyd Mayweather - but he celebrated leaving the ring legend with a black eye.
Mayweather took his time to bring an end to the bout in Dubai - but once he put his foot on the gas there was only going to be one conclusion. Pinning Deji in the corner of the ring, he forced referee Kenny Bayless to step in and end the bout in the sixth round.
But by then Deji had inflicted a wound under Mayweather's left eye which could well swell up and blossom into a bruise. And the YouTuber was not going to miss the opportunity to gloat as he took to social media to write: "I gave Floyd Mayweather a black eye."
Mayweather later laughed off the injury, saying: "That's cool, we had fun tonight. You guys wanted to see a little something. I had to close the gap and when you close the gap that happens." Earlier, the 45-year-old had praised his opponent, saying: "I'm glad that Deji landed a good shot. This is part of fighting, this is part of entertaining. Everyone wanted to see entertainment and that's what we have them tonight.
"I always want you to go after your dreams and what you believe in. I didn’t get to where I got to overnight. I had a great time, I couldn’t do it myself. Deji, you are a tough competitor, I'm proud of you, keep up the great work."

Deji was facing by far the toughest test of his short career having won just one of his previous four bouts against fellow social media stars. And he dared to call out pop icon Justin Bieber after the fight was waved off. "I' wouldn't mind fighting Justin Bieber, Liam Payne, anyone who wants it really, I'm on all the smoke," he said.
"I feel good. It was an early stoppage, I wanted to carry on but boxing is boxing and I understand. It feels good, honestly. I'm tough; this whole experience has been eye-opening. I love boxing and it's just insane, from where I was to where I am now."
