Denver Nuggets All-Star forward Paul Millsap will undergo surgery on his left wrist and will be sidelined two to three months, league sources told The Vertical.

Millsap suffered the injury in the Nuggets’ road loss to the Los Angeles Lakers on Sunday night. Initial X-rays returned clean, but Millsap had further tests over the past two days that confirmed the need for surgery, league sources said.

Denver is currently 10-7 in the Western Conference standings, and Millsap’s injury is a significant blow because of his reliable production and leadership as the starting power forward.

Millsap signed a three-year, $90 million deal to join the Nuggets in July, a prized signing to complement the young core of Nikola Jokic, Jamal Murray and Gary Harris. In 16 games this season, Millsap has averaged 15.3 points, 6.2 rebounds and three assists.

Millsap, 32, was an All-Star in each of his previous four seasons with the Atlanta Hawks, leading the team to a 189-139 record and an Eastern Conference finals appearance in 2015. He has played 12 NBA seasons.
