Why was the fight ruled a KO? How did Vitali "stop" Solis?

Idiotic statement.

He lost his equilibrium when his head buckled, from a punch he didn't see coming.

And he twisted his leg and got injured. GET OVER IT.

Correct. If you are injured and you weren't fouled, you lose if you can't continue. One of the oldest rules in boxing.

Its not Vitali's fault that Solis's knee can't handle is body weight. By definition Vitali should've won by TKO because the ref had to stop the fight.
