A CT scan has revealed that Portland Trail Blazers guard CJ McCollum has a collapsed right lung, known medically as a pneumothorax, the team announced Tuesday.

McCollum sustained the injury during the 4th quarter of Portland's game against Boston on December 4.

A pneumothorax is a collapsed lung that occurs "when air leaks into the space between your lung and chest wall," according to the Mayo Clinic. 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.

In 24 games this season (all starts), McCollum has averaged 20.6 points 4.1 rebounds, 4.5 assists, 1.08 steals in 35.3 minutes.
