According to Keith Smith of Spotrac.com, Boston Celtics forward/centerXavier Tillman Sr. (illness) will not play against the Chicago Bulls on Thursday due to an illness. Tillman's absence shouldn't impact the Celtics' rotation, as he's averaged just 8.6 minutes across 17 games so far in this year's campaign. With Tillman and Sam Hauser (back) both out, players like Neemias Queta and Jordan Walsh could soak up a few extra minutes on Thursday.
