Isaiah Hartenstein missed the first month with a fractured hand — and now will miss at least a week with a calf strain. The Thunder are back to their small-ball era. The gap between Holmgren's injury and Hartenstein's return lasted over a week in Nov.

Oklahoma City Thunder center Isaiah Hartenstein is out at least a week with a calf issue and will be re-evaluated after that.

The Cavs snapped Oklahoma City’s franchise-record 15-game win streak at Rocket Mortgage FieldHouse. The Thunder will look to avenge that loss without Hartenstein and Chet Holmgren, who’s missed the past 29 games due to a pelvic fracture.
