In the midst of a rough stretch in which the team has lost six of its last seven games, the Trail Blazers will have a tougher road ahead with the loss of another star player.
Guard CJ McCollum was diagnosed with a collapsed right lung—formally known as pneumothorax—the team announced Tuesday night. McCollum suffered the injury during Saturday's 145–117 loss to the Celtics.
McCollum played just 47 games a year ago after suffering a fractured foot in January.
The 30-year-old shooting guard has averaged 20.6 points and 4.5 assists on 39.3% shooting on three-point attempts through 24 games this season.
