The referee called that fight exactly right Cook was in no fit state to continue.It was a tragedy for Cook but all credit to Martinez what an uppercut that was.
I truly think many of the people that becall referees saying they stop fights too early have never boxed themselves. I'd much rather a referee stops a fight a bit early than a bit too late. Think back to Gerald McClellan Beathavaen Scotland, Duk Koo Kim etc. Thats what can happen when fights are let to go too long
