On Wednesday, the Oklahoma City Thunder announced that center Isaiah Hartenstein (calf) sustained a left soleus strain in Tuesday's game against the 76ers and he will be re-evaluated in one week, according to Tim Bontemps of ESPN.com. The 26-year-old German center is out until at least the Jan. 22 matchup with the Jazz. Until the big man returns, Jaylin Williamswill see plenty of extra minutes at center.
