Oklahoma City Thunder center Isaiah Hartenstein sustained a small, non-displaced fracture in his left hand and will be re-evaluated in five-to-six weeks, the team announced Thursday.

The left-handed Hartenstein was injured during Oklahoma City’s 124-94 preseason victory over the host Denver Nuggets on Tuesday.

Signed to a three-year, $87 million contract this summer, Hartenstein averaged 7.8 points and 8.3 rebounds in 75 games (49 starts) last season for the New York Knicks.

A journeyman to start his NBA career, Hartenstein has averaged 6.0 points and 5.6 rebounds in 322 career games (61 starts) with the Houston Rockets, Nuggets, Cleveland Cavaliers, Los Angeles Clippers, Knicks and Thunder. He was selected by the Rockets in the second round of the 2017 NBA Draft.
