When should a fighter be pulled out ?

[Master]

When they have taken a severe beating and have nothing left to offer and the ref and corner men say so.

Missys post was about all there is to it, completely depends on the fighter, the relationship with their trainer and the particular matchup. I would imagine many fighters wouldn't sit well with having a fight stopped unless they completely accept defeat themselves, it's always easier to have a scapegoat for failure and such. Trainers need to make a living to, it's probably a fine line that way.
