First of all broken noses in boxing are relatively rare. Most when they do happen are not that severe. Just with any other injury, no two are ever the same. We have had a boxing gym for over 25 years and we have yet to have a single broken nose. Lots of bloody ones but not single broken one. I have had my nose broken at least 3 times but never while boxing. Mine happened playing football. I have been reading the post about Mikey Garcia not being able to continue after his nose was broken from a headbutt. I know for certain that those critical of the stoppage have never suffered a broken nose. Even a minor tear of the cartlilage is painful and causes a lot of bleeding. The last time my nose was broken. My nose was dislodged and the cartilage completely blocked my right nostril and I could not breath out of either nostril. Both my eyes were immeditately swollen. It required surgery and a full week of having both nostrils packed to heal. A severely broken nose can be career ending and can also be life threatening.
