Who is the toughest boxer ever?

[Cutthroat]

^^^ I thought Ali broke his jaw vs. Ken Norton...I could be wrong.

Maybe, I can't remember, still an amazing performance in both fights though.

Boxers were tough as nails in the past.

Erik Morales has to be mentioned as one of the toughest , he took some huge punishment without going down until Pacquiou 2. And Matthew Saad Muhammad was super tough.

It was Norton who broke Ali's jaw. I looked it up.
