Ben Simmons will need three to four months of rehabilitation after having back surgery on Thursday, but is expected to be fully recovered in time for the preseason training camp in September, according to sources.

Simmons is having a microdiscectomy procedure to address pain in his lower back, the Nets said in a release.

The team said that the decision to have the surgery was reached after consultation with multiple back specialists.

Simmons never played a game for the Nets after he was traded to the 76ers. Simmons had planned to return for Game 4 of the Nets' Eastern Conference first-round series against Boston Celtics, but a week of pain-free days ended with pain on the eve of Brooklyn's elimination.

Simmons and his agent, Rich Paul, met with Nets general manager Sean Marks and team officials the following day, agreeing to work together to try and return Simmons to the court next season.

Simmons will not be able to progress on a 2022-23 return after having surgery.

Simmons has three years and $114 million left on his contract after this season.
