Williams (knee) is doubtful for Thursday's game against Memphis due to left knee injury management, according to the Trail Blazers.
Williams is trending toward missing Thursday's matchup as Portland continues to manage his left knee. The veteran center's availability has been an ongoing concern in recent seasons, and the team appears to be exercising caution with his workload. If Williams is ruled out, Donovan Clingan could see additional minutes in the frontcourt.
