Starting center Mark Williams has been diagnosed with a stress reaction in the third metatarsal bone in his left foot, the Suns announced in a press release (Twitter link via Law Murray of The Athletic).
Williams, who will be a restricted free agent this summer, will be reevaluated in two-to-three weeks, per the team.
It’s unclear when Williams’ injury occurred. He played 22 minutes in Tuesday’s 11-point victory at Sacramento at Sacramento.
After two college seasons at Duke, Williams was selected by the Hornets with the 15th overall pick in the 2022 draft. The 7’1″ big man struggled with injuries over the course of his three years in Charlotte, appearing in just 106 games, prior to being traded to Phoenix last offseason.
The Suns developed a plan to help Williams stay on the court and it had worked well to this point in the season. The 24-year-old has appeared in a career-high 56 games in 2025/26, only missing five contests with the Suns currently sitting at 35-26.
However, Williams’ stress reaction will keep him sidelined for the foreseeable future. While he’ll be checked out again in a few weeks, there’s certainly no guarantee that he’ll be ready to return at that point — it will be difficult for Williams to stay in game shape given he has a foot injury.
Phoenix plays nine times between March 5 and March 19, and Williams is likely to miss all of those games. A three-week absence would result in Williams missing 12 games.
In his 56 appearances this season, Williams has averaged 11.6 points, 8.1 rebounds, 0.9 steals and 0.9 blocks in 23.6 minutes per game. He’s shooting 63.3% from the floor and 76.7% from the foul line.
Backup center Oso Ighodaro will likely replace Williams in Phoenix’s starting lineup, with rookies Rasheer Fleming and Khaman Maluach among the candidates for more minutes off the bench.
Maluach time
Big men with foot problems. Not a recipe for a long career.
