Portland Trail Blazers star Damian Lillard has had surgery to address a lingering abdominal injury, the team announced Thursday.

The procedure, which was performed by Dr. William Meyers in Philadelphia, is likely to keep Lillard out at least 6 to 8 weeks, sources told ESPN. The team on Thursday said his status would be re-evaluated in six weeks.

Lillard last played on Dec. 31.

Portland is in 10th place in the Western Conference and the team is 4-7 without Lillard this season. Fellow backcourt star CJ McCollum is out indefinitely after sustaining a collapsed lung.

Lillard aggravated his abdominal injury playing for Team USA at the Tokyo Olympics last summer. He has battled the issue throughout the season as his shooting and scoring numbers have taken a dip. The six-time All-Star is averaging 24 points and 7.3 assists in 29 games.

The Blazers start a six-game road trip Thursday.
