Duren (thigh) exited Friday's 128-111 win over the Heat in the second quarter and did not return, finishing with four points (2-4 FG), six rebounds, three assists, one steal and one block across 10 minutes.
Duren was deemed questionable to return with a right thigh injury after exiting to the locker room, and he never checked back in. If the big man is forced to miss additional time, Paul Reed would likely step into the starting five. Duren's next chance to play will come Sunday at Philadelphia.
