The classy display of gentlemanly conduct shown between boxers Anthony Joshua and Wladimir Klitschko went some way in repairing the game's slightly checkered public perception.
But it's going to need some good PR to mend the damage of this latest drama.
Eight rounds into a super middleweight title bout between American Andre Derrell and Venezuelan Jose Uzcategui, the latter was disqualified after a seemingly-legitimate knockout punch was deemed to have been thrown after the bell rang.
While confusion reigned in the ring, Andre Derrell's uncle, Leon Lawson, decided to exact justice in the scummiest way possible.
Here's the punch again in slow-mo...
Taking the shot like a champ, Jose Uzcategui has since filed assault charges against Lawson, which could see him sentenced to up to 25 years in jail.
Defending his uncle after the furore, Dirrell said on CBS: "I'm very sorry for what my coach has done. But he loves me.
"That's my man, that's my uncle, that's my brother, that's my coach."
That's one way to put it, we suppose.
