Michael Porter Jr. had already undergone one back surgery prior to being selected by the Denver Nuggets in this year's draft, but now he has undergone another.

The Nuggets announced that the 14th pick in the 2018 NBA draft has undergone surgery of the lumbar spine at The Carrell Clinic in Dallas, Texas.

The Procedure was performed by Dr. Andrew Dossett, but at the moment, there is no timetable for his return to the court.

This is the second back surgery which Porter has undergone in the past 12 months, as he had a microdiscectomy of his L3-L4 spinal disks in November 2017.

Despite the procedure, the Nuggets have no plans to sit Porter out for the entire year, according to Steve Aschburner of NBA.com.

Porter was considered to be a high draft pick, but his draft stock took a serious hit after he missed the majority of his only season at Missouri due to the first back surgery mentioned above. A hip strain and back spasms also played a part in this draft stock tumble too.

Now with this second surgery, there is a chance that the rookie could miss some games, despite what the Nuggets might say. However, they're prepared for this eventuality.

Denver narrowly missed out on making the Western Conference playoffs last season for the first time in five years, losing the eighth seed to the Minnesota Timberwolves in the final game of the year.

However, with all of their main players back, a healthy Paul Millsap, and the addition of Isaiah Thomas, the Nuggets are in good shape, even without Porter.

If Porter is able to return and contribute towards the Nuggets season at the standard of the number one overall pick which he was predicted to be before his surgeries and injuries, then the franchise might find themselves back in the playoffs for the first time since 2013.
