Don't know, but the moment I heard the hospital was keeping him overnight, I feared he had a punctured lung.So is it A rib or MANY ribs? Because obviously with the number of ribs broken the recovery becomes more arduous and involved, much more serious.
Rib injuries are common in boxing, for obvious reasons, deep bruises occur in sparring with regularity and broken ribs are as common as a broken nose or a busted lip, so I had some experience with this in my amateur boxing days and the hospital usually sends you home unless the X-Rays suggest a punctured lung, then they keep you for a cat scan and further testing and to make sure its not life threatening.
