Portland Trail Blazers shooting guard CJ McCollum has been diagnosed with a collapsed right lung after undergoing a CT scan, the Blazers announced on Tuesday night.
McCollum did not travel with the Blazers ahead of Wednesday night's game against the Golden State Warriors. He will continue to be evaluated before a prognosis is made, according to the team.
McCollum suffered the injury in the fourth quarter of Saturday's blowout loss to the Boston Celtics. He sat out of Monday's loss to the Los Angeles Clippers due to what the team listed as bruised ribs.
In his ninth NBA season, McCollum has averaged 20.6 points, 4.1 rebounds and 4.5 assists through 24 games.
