word is he has a deflated lung, not apunctured one.  still sucks.  basically there is a vacum in the chest cavity that keeps the lung inflated,and when he cracked the rib, he lost the vacum (and no thats not spelled right, nothing looks right), so the lung is kinda flopped.  i think they just insert a tube w/ suction in between the ribs to re-establish suction, and the lung puffs back up.  then the hole for the tube just has to heal back up, and hes set aside from bones
