This is Deontay Wilder, an undefeated heavyweight champion boxer who is obviously good at knocking people out.
And this is Charlie Zelenoff, a self-proclaimed world champion "human cyborg."
Zelenoff has reportedly spent the last couple of years trolling and abusing Wilder through social media and the phone with racist taunts and verbal attacks on Wilder's daughter, who suffers from spina bifida.
Recently, Wilder challenged Zelenoff to a fight which Zelenoff accepted.
Wilder was quite relentless in his assult, with Zelenoff spending a lot of time on the floor.
It can only be hoped that Zelenoff learnt to never taunt championship boxers unless you are willing to deal with the consequences.
