Michael Porter Jr., who was taken by the Denver Nuggets with the 14th overall pick in the 2018 NBA Draft, has undergone surgery of the lumbar spine, the team announced Thursday.
The Nuggets said there is no timetable for Porter's return to basketball participation.
The procedure was performed by Dr. Andrew Dossett at The Carrell Clinic in Dallas, TX.
This is the second back procedure for Porter who played in just three games as a freshman at Missouri due to a back injury. He originally had a microdiscectomy of his L3-L4 spinal disks in November of 2017 and was expected to miss the rest of the season.
