Kyrie Irving has already missed 10 games over nearly three weeks with a shoulder injury and multiple sources say he could need a few more weeks.

Irving is out with what the Brooklyn Nets have termed a shoulder impingement.

One medical source not affiliated with the team intimated there’s more under the surface and that this injury could be even more long term.

“That’s a very, very broad term,” said Dr. Andrew S. Rokito, chief of shoulder surgery at NYU Langone Orthopedic Hospital. “Impingement typically does not refer to an acute injury. [It] refers to more of a long-standing, chronic issue with the rotator cuff.

“He could have a rotator cuff injury which could be just tendinitis and inflammation all the way up to a partial tear. It’s unlikely a full tear. … In terms of time off, I can’t answer that question. It’s certainly conceivable if he really hurt his shoulder with an injury to the rotator cuff he may need few weeks.”

The injury is typically associated with wear-and-tear and is unusual for a player as young as Irving at 27 years old.
