Isaiah Hartenstein reaches out for a rebound

Oklahoma City Thunder center Isaiah Hartenstein will be out for at least a month after suffering a small, non-displaced fracture in his left hand during a preseason game in Denver.

The Thunder announced on Thursday that Hartenstein, who got injured in Tuesday’s game, will be re-evaluated in five to six weeks.

The Thunder signed the 7-foot, 250-pound Hartenstein as a free agent in the offseason to improve their rebounding and add some size, which was two of their weaknesses last season when they secured the No. 1 seed in the Western Conference playoffs. He averaged 8.5 points, 7.8 rebounds, and 3.5 assists last season with the New York Knicks.
