Dosunmu isn't dealing with an injury but will sit out Friday's preseason finale against the Bulls for rest purposes, Jon Krawczynski of The Athletic reports.
Dosunmu won't travel with the Timberwolves but is expected to be ready to go for their regular-season opener against the Heat on Wednesday. With the 26-year-old sidelined, Terrence Shannon, Isaiah Evans and Bones Hyland could see increased playing time.
