After "knocking out" Logan Paul, a YouTube boxer, UFC fighter Paulo Costa was made famous.
Paul released a clip of him being flattened in 2020 by Costa, while he was training for his own UFC career.
Costa threw an attack across Paul, which sent him down
Some have questioned whether or not the knockdown was real
Paul was hurt by a boxing sparring session. A right hook landed on him. Trainers ran into the ring to help him get up.
Costa can also be seen wrestling with YouTuber Floyd Mayweather, who fought him in an exhibition bout last January. There was no winner declared.
Paul was defeated by KSI, a British YouTuber in his first professional fight.
He expressed a desire for MMA crossover and stated that he would like to speak with Scott Coker to discuss signing a contract with Bellator.
He said, "We love Scott - let’s have that meeting."
He also met Costa, a Brazilian fighter who is ranked No.5 at the middleweight division.
Many people found the clip hilarious online. However, others raised doubts about claims that Costa's punch to Paul was not real.
Chico, a Twitter user wrote: "Watching Logan Paul get knocked out in the UFC by a fighter made my entire day."
Mitch commented: "Love it. Logan Paul needs to be knocked out even more.
Jacob said, "Something KSI could't do."
One skeptical fan wrote, "I'm sorry Logan, but this is THE FAKEST KNOCKOUT EVER SEEN" - slow motion 0.25x Paulo didn’t even connect the punch, and you can’t get knocked unconscious if you get hit in your shoulder. You deserve an Oscar!
