Holmgren, Isaiah Hartenstein (calf) and Jaylin Williams (shoulder) are all questionable for the first game of this back-to-back, and the second game being against the Spurs could certainly be a factor there. The center rotation is certainly up in the air, with the only one guaranteed to be healthy is Branden Carlson, who could play a significant role if more than one of the aforementioned bigs is sidelined.
