Wallace (shoulder) will not return to Sunday's game against the Clippers, Rylan Stiles of SI.com reports.
Wallace exited for the locker room with an apparent left shoulder injury during the first quarter and will not be able to return. Jared McCain and Ajay Mitchell figure to see expanded roles with Wallace out. The Thunder play the second half of their back-to-back set Monday against the Suns, so it wouldn't be surprising for Wallace to miss time.
