Suns center Mark Williams sustained a torn labrum in his left shoulder during an offseason workout, according to Shams Charania of ESPN, who reports (via Twitter) that the big man underwent surgery on Thursday to repair the tear.

While there’s no specific timeline for Williams’ return to the court, it’s safe to assume he’ll be sidelined for at least part of the regular season. Charania says the big man is expected to miss an “extended period,” while plugged-in Suns reporter John Gambadoro of Arizona Sports 98.7 tweets that the recovery process will take a “considerable amount of time.”

Gambadoro adds (via Twitter) that Williams will likely end up missing several months, which would be consistent with the recovery timelines for other NBA players who have suffered similar injuries in recent years.

After being plagued by a series of foot and back issues in his first three NBA seasons for the Hornets, Williams appeared in a career-high 60 regular season games for the Suns last season after being traded from Charlotte to Phoenix during the 2025 offseason. The former 15th overall pick played in just four games after March 3 due to a stress reaction in his left foot, but posted solid numbers on the season, making 55 starts and averaging 11.7 points, 8.0 rebounds, and 0.9 blocks in 23.6 minutes per night.

Williams earned a qualifying offer from the Suns in June, making him a restricted free agent, then quickly agreed to terms with the club on a three-year, $38MM contract. That deal is fully guaranteed and will run through the 2028/29 season.
