Denver Nuggets announced on Monday that forward Michael Porter Jr. will undergo surgery to address his latest injury but there’s no return timetable chalked out yet. Meanwhile, Porter’s agent, Mark Bartelstein, said the surgery is scheduled for Wednesday.

Porter, who had a terrible back condition in college that made some doubt if he’d ever be able to play in the NBA, has only played in nine games this season.

Doctors will then be able to estimate Porter’s likely recovery path and how much time he will need to return. However, initial reports suggest Porter could miss the entirety of the season.

On Monday night, the Nuggets begin a seven-game road trip in Miami. They’re on a six-game losing streak, with five of those losses being by double digits.

This season, Denver has already seen seven players miss time due to injury, including reigning MVP Nikola Jokic and All-Star guard Jamal Murray. Murray hasn’t played since breaking the ACL in his left knee last season, while Jokic has been suffering from a wrist injury.

Porter was restricted to three games in his lone collegiate season at Missouri due to back ailments, and despite initially being regarded as a viable contender for the No. 1 overall choice, he slid to 14th in the 2018 NBA draught.

After missing his entire rookie season with the Nuggets due to back surgery, he has exploded since then.

Porter has averaged 14 points per game in 125 NBA regular-season games and 17.4 points per game in last season’s playoffs, earning him a five-year agreement for at least $173 million in September. The season-long extension starts next season. Prior to the injury, Porter was off to a rough start this season, averaging 9.9 points and 6.6 rebounds on 35.9% shooting from the field and 20.8% from 3-point range through nine games.
