The New Orleans Pelicans announced that guard CJ McCollum has a small pneumothorax in his right lung after imaging was done on Sunday morning.
According to the Mayo Clinic, a pneumothorax "occurs when air leaks into the space between your lung and chest wall. This air pushes on the outside of your lung and makes it collapse. A pneumothorax can be a complete lung collapse or a collapse of only a portion of the lung."
This is the second time in McCollum's career where he's dealt with a pneumothorax. He had one with Portland diagnosed in Dec.
