The Seattle Storm released a statement on Sue Bird Tuesday afternoon, confirming that the 11-time WNBA All-Star and front office associate for the Denver Nuggets will undergo a procedure on her left knee to remove a loose body.

Fansided’s High Post Hoops reported the injury before the statement, which they included excerpts of in the story below.

UPDATE [1:08 PM EST] The Storm, in a press release, said that Bird will undergo surgery to remove a loose body in her left knee, and will be out indefinitely.

“The most important thing to us is that Sue is healthy and strong,” Storm CEO and GM Alisha Valvanis said in the release. “Based on her feedback and evaluation from her longtime surgeon and our medical team, it was determined the best course of action was a scope. We have confidence this will support Sue’s full recovery and we look forward to her return to the court.”

The team also announced that Bird will do her rehabbing in Seattle.

“I’m super disappointed to have to miss time with the team this season,” Bird said in the release. “There’s nothing I want more than to be on court with my teammates defending our title. I’ve been down this road before, so now I just have to focus on getting better so I can continue to represent the Storm, the city of Seattle and the ‘Storm Crazies’ in the future.”

Bird had just completed her first season of what was essentially an apprenticeship with the Nuggets’ front office, but always intended on coming back to compete in the WNBA this season. Bird is out indefinitely, per High Post Hoops.
