Oklahoma City, Dec. 29, 2025 — Oklahoma City Thunder center Isaiah Hartenstein will be out of action after re-injuring his left calf, the team announced Monday.
Hartenstein left Sunday’s 111-103 victory over the Philadelphia 76ers late in the third quarter and was ruled out for Monday night’s matchup with the Atlanta Hawks. The Thunder did not provide a timetable for his return.
The 7-footer had already missed six games earlier this season after straining the soleus muscle in the same calf on Nov. 26, returning 17 days later.
Through 32 appearances, Hartenstein is averaging 11.2 points and a team-best 10.4 rebounds for the defending NBA champions, who lead the league at 27-5.
Oklahoma City’s frontcourt depth is further tested by the continued absence of reserve center Jaylin Williams, sidelined for a seventh straight contest with right heel bursitis.
