The procedure will be done Thursday. The Nets said it was decided upon after consultation with multiple back specialists.
Simmons sat out this entire season. The No. 1 pick in the 2016 draft didn’t play in Philadelphia after requesting a trade, citing mental health concerns. After he was dealt to Brooklyn in February in a deal for James Harden, he was bothered by the back while trying to rebuild his conditioning.
The Nets originally said he had back spasms but later said the problem was a herniated disk. Simmons eventually resumed workouts and hoped to make his debut during the playoffs, but that plan was scrapped when he experienced more pain.
Simmons will have a microdiscectomy, in which a small fragment of the disk is removed.
The Nets said further updates will be provided after the procedure.
