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 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.
