Has a sparring session ever ended up like Castillio-Corrales, Ali-Frazier 3...?

[ICEMAN JOHN SCULLY]

You'd be surprised how many pro boxers and even champions get Ko'd in sparring. Nevertheless sparring is for learning not wars. Wars can be a bad thing cause Abregu looked awful vs Sadam Ali but he was supposedly havijg sparring wars with Matthysse leading up to that fight.

Sometimes you don't need to learn how to box. Sometimes you need to learn how to fight. Sometimes you have no choice. You need to know if you can handle the pressure for the real pressure comes

Canelo has knocked people out in sparring and there were rumours he actually killed one of his sparring partners last year when he was training for Angulo
