The Thunder’s frontcourt just got another reminder of why Isaiah Hartenstein mattered so much in their offseason plans.
On Wednesday, Oklahoma City announced that Thomas Sorber underwent a minor arthroscopic procedure on his right knee. The operation was successful, and he is expected to return to on-court activity in roughly a month.
That update lands with extra weight because Sorber has already had a lost start to his Thunder career. The 15th overall pick in the 2025 NBA Draft has not played a single minute of meaningful action for Oklahoma City after suffering a torn ACL before last season began.
For a team trying to sort through a shaky center situation, that is no small thing.
Sorber’s latest knee procedure is another jolt to a frontcourt that has already spent plenty of time on the injury report. Even if this kind of surgery is a normal part of ACL rehab, it still serves as a harsh reminder of how thin the Thunder have been up front.
That’s where Hartenstein comes back into the picture. After months of speculation about his future, Oklahoma City declined his team option for 2026-27 last week, then immediately brought him back on a new three-year, $75 million deal. What might have looked at first like a possible exit turned into a clear commitment, with Sam Presti and company deciding to keep the 28-year-old through 2028-29.
Given everything that has happened since, that choice looks even smarter now.
The Thunder have been dealing with frontcourt uncertainty for a while. Sorber was redshirted for his first season because of the knee injury.
Chet Holmgren missed all but 32 games two years ago because of a right iliac wing fracture. And Aday Mara, the lottery pick from this summer’s draft, has already said it may take him time to adjust to the NBA and become the player Oklahoma City drafted him to be.
That is a lot of moving parts for a team with championship ambitions.
Hartenstein gives them something steadier to lean on. Over his two-year tenure, he has averaged 10.3 points, 10.1 rebounds and 3.7 assists per game, and he served as the starting center during the Thunder’s championship run.
With the big-man room still looking volatile, keeping him around was about more than finances or apron math. It was about making sure the roster had a reliable anchor in the middle.
For Oklahoma City, more options in the pivot rotation is not a luxury. It’s a necessity.

Thunder Bringing Back Kenrich Williams Says More Than It Seems
Kenrich Williams is coming back to Oklahoma City, a familiar move for a Thunder team that has spent the summer balancing continuity with the realities of a title-contending roster. The veteran forward has been part of the organization since the 2020 Steven Adams trade, and his return gives the Thunder another trusted piece who knows the system, the standards and the day-to-day expectations inside the building.
The deal also says something about where Oklahoma City is willing to go to keep that stability intact. After declining Williams team option for the 2026-27 season, the Thunder agreed to a new one-year contract that should help sort out the final roster spot, even if it edges them further into the luxury-tax picture. For a team in this position, those kinds of decisions are rarely just about one player. [Read more 🡒]
Thunder Starting Five Suddenly Feels Less Settled Than Fans Expected
The Thunders offseason has already done plenty to reshape the depth chart around its core, and the front office has not been shy about making moves that hint at how the next roster will be built. Oklahoma City drafted three players, dealt away a pair of bench scorers, kept Isaiah Hartenstein in place and picked up Luguentz Dorts team option, all while keeping the focus on a competitive group centered on Shai Gilgeous-Alexander, Chet Holmgren and Jalen Williams.
Even with that core firmly established, the opening-night starting five is not as locked in as it once looked. Projections have Cason Wallace in the fifth spot alongside Gilgeous-Alexander, Williams, Holmgren and Hartenstein, but the Thunder still have enough flexibility, and enough young talent, that the final call could shift as the roster settles and roles sort themselves out.
