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

The Oklahoma City Thunder have announced that Isaiah Hartenstein suffered an injury against the Philadelphia 76ers and will be re-evaluated in one week. The Thunder will have a tough time navigating this stretch without the big man.

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.

The Thunder have plenty of options. None will equate to Hartenstein but enough to survive this upcoming stretch. OKC has flexed its rubber-band-esque ability to stretch and transform its identity. It will be asked to do so again.

Thunder center Isaiah Hartenstein suffered a left calf strain Tuesday night against the 76ers and will be re-evaluated in about one week.

The OKC Thunder will be without Isaiah Hartenstein in Thursday's matchup with the Cleveland Cavaliers, the team announced. He will be re-evaluated in approximately one week.

It was a happy return to Manhattan for Isaiah Hartenstein, whose Oklahoma City Thunder dismantled the Knicks by a 126-101 final on Friday night at Madison Square Garden. The Western Conference-leading Thunder earned a two-game sweep of the Knicks after previously prevailing in a 117-107 home win last weekend.

Twenty-one games into his tenure with Oklahoma City, Isaiah has adapted. Still, playing at Madison Square Garden for the first time since Hartenstein signed a three-year deal, $87 million contract with the Thunder, the venue Isaiah called home for two seasons, is unique.
