Head coach Micah Nori said that Krejci suffered a left leg fracture during Wednesday's 132-119 win over the Suns, Brett Siegel of ClutchPoints.com reports.
Nori did not provide a timetable for Krejci, but it's safe to say that he won't be back soon. His minutes figure to be divvied up amongst Chris Youngblood and Sidy Cissoko.
