Mavs’ Dante Exum To Undergo Season-Ending Knee Surgery

Dante Exum‘s 2025/26 season has come to an end before it even began, according to the Mavericks, who announced today (via Twitter) that the veteran guard will undergo season-ending surgery.

According to the Mavs, Exum – who had yet to play at all this fall – has continued to deal with complications related to an offseason procedure on his right knee. It has been determined that a follow-up surgery is necessary to address the issue.

It’s the latest in a long line of injuries that have limited Exum’s availability over the course of his professional career. After playing all 82 games as a rookie, the former fifth overall pick missed his entire second NBA season in 2015/16 due to a torn ACL, then was plagued by shoulder, ankle, and knee issues in subsequent years.

Exum rebuilt his value by playing in Europe from 2021-23, then returned stateside during the 2023 offseason and has been in Dallas since then. The 30-year-old has been a very effective role player for the Mavs when healthy, averaging 8.0 points, 2.8 assists, and 2.4 rebounds in 19.5 minutes per game, with a shooting line of .516/.472/.768.

However, he has been made just 75 appearances since the start of the 2023/24 season, including just 20 in ’24/25 due to right wrist surgery and a broken left hand.

With the Mavericks’ front office very much in the news as of late, the team’s handling of Exum in recent months deserves some scrutiny, notes Grant Afseth of Dallas Hoops Journal (Twitter links).

As Afseth points out, the Mavs never publicly disclosed Exum’s offseason knee surgery before today and had to use the stretch provision to waive Olivier-Maxence Prosper‘s guaranteed $3MM salary in order to create enough room under their hard cap to bring back Exum on a guaranteed minimum-salary deal. Given Exum’s injury history, that was a risky move, especially considering that Dallas badly needed backcourt depth while Kyrie Irving continued to recover from his ACL tear.

While the Mavs could waive Exum to open up a spot on their 15-man roster, they won’t have enough room under that hard cap to sign a replacement until January, barring a separate cost-cutting move. If Exum remains on the roster, Dallas could apply for a disabled player exception, but it would be worth just half of the guard’s salary, making it too small to be of much real use.
