(Portland, OR) -- Blazers point guard Damian Lillard's abdominal injury is going to keep him sidelined even longer. ESPN is reporting that Lillard will have surgery to address his lingering abdominal injury. The procedure will reportedly keep Lillard out for at least 6-to-8 weeks. The 31-year-old guard aggravated the injury while playing for Team USA in the Tokyo Olympics last summer and has not played since December 31st. Portland is 16-and-24 and is also dealing with the absence of CJ McCollum, who has missed time with a collapsed lung.
