The Houston Rockets are working to sign Isaiah Hartenstein to an NBA deal.

Hartenstein, a 7-foot center, played for the Rockets' Rio Grande Valley affiliate with a G League contract last season.

Hartenstein was Houston's second round pick in 2017 and could have chosen to return to Europe. Hartenstein, 20, had played with Zalgiris Kaunas in the Lithuanian league before he was selected by the Rockets.
