As boxing fans railed against Teerachai Sithmorseng, accusing him of throwing his match with Lucas Matthysse on Saturday, the Thai fighter was being stretchered out of the arena and into a waiting ambulance.
Earlier, the Buri Ram boxer -- announced by US TV under his birth name of Tewa Kiram but better known here as Teerachai -- was judged a knockout loser to Argentinian Matthysse in a California bout for the vacant WBA welterweight title.
In a bizarre finish to the fight, the Thai, who formerly fought as Teerachai Kratingdaenggym (in homage to his former gym), took a jab, threw a punch and then collapsed in a delayed reaction.
Upon watching replays, fans were quick to cry foul, and also pointed out that a small jar of balm-like substance had been confiscated from Teerachai's corner after the sixth round, precipitating a downturn in form in a fight he was previously boxing well in.
On the latter point, the use of a balm -- if that is all it was -- as an inhalant was likely just an innocent mistake.
It is common practice in boxing and muay Thai matches here, but Teerachai had never fought outside Thailand before and, according to the US commentators, his team had never worked a corner overseas either.
They probably just didn't know this is not allowed in some other countries, and nobody thought to tell them this was the case.
That Teerachai lost a round and a half later is surely a coincidence, even if the finish to the fight was unusual.
But a fix? Not at all.
The concluding knockdown was the second of round eight, and while it appeared, with the benefit of video replay, unconvincing, there was nothing dodgy about the first knockdown.
Matthysse, a renowned puncher, detonated a right hand to the temple that levelled Teerachai. It looked an instant finisher, but somehow the Thai managed to clamber erect and then start firing back.
If ever there was a moment to surrender, it was when Teerachai was lying flat on his back, arms spreadeagled, with half of his body outside the ropes. Anybody looking to lose a fight does not get up from that.
It was the kind of punch that has a lasting effect. Temple shots can upset equilibrium and, yes, have a delayed effect.
It was in all likelihood this blow which caused Teerachai to collapse again later in the round, rather than the relatively innocuous jab credited with the delayed knockdown that finished the fight.
The same video replay which caused fans to doubt the legitimacy of the result also shows Teerachai blink and shake his head prior to the second knockdown -- an indication that he was struggling to regain his senses.
That he was later taken to hospital surely proves the trauma was real.
There will likely be an investigation into what substance was used in Teerachai's corner, but I'll be very surprised if any evidence of foul play turns up.
The authorities will also, I'm sure, be satisfied that the finish to the bout was on the level.
Conspiracy theorists are being disrespectful to a fighter who gave his all, and took a punishing blow from a world- class puncher.
