Celtics backup center Robert "Time Lord" Williams tested positive for coronavirus, requiring their starting center, Tristan Thompson, and a backup foteard who plays a lot, Grant Williams, to sit tonight. They will be playing with one regular over 6' 8", Daniel Thies. They brought up Tavko Fall from the G league team. A lot of time they use Smart on centers, but with Kemba and the backup point guard Jeff Teague also out, I don't see that look. Probably will see a lot of Pritchard, a rookie from Indiana who is already in the rotation.
