Michael Porter Jr. has undergone lumbar spine surgery performed by Dr. Andrew Dossett at the Carrell Clinic in Dallas. Porter has now undergone three surgeries on his back.

Porter will be out indefinitely.  

Porter previously missed his first season in the NBA following back surgery.

“They went into surgery hoping to find exactly what they found,” Porter’s agent, Mark Bartelstein, told The Denver Post. “It went great. He can already feel a difference.”

Porter's five-year, $172 million max contract extension with the Nuggets includes $145 million guaranteed.
