Ben Simmons will undergo back surgery on Thursday and require three to four months of rehabilitation. Simmons is expected to be fully recovered before the start of training camp.

Simmons will undergo a microdiscectomy procedure to address pain located in a herniated disk in his lower back.

The decision to undergo the surgery was reached after "consultation with multiple back specialists," the Brooklyn Nets said.

Simmons made multiple attempts to return to NBA action following his trade to the Nets in February. 

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