Doncic will not return to Wednesday's Christmas Day contest due to a left calf strain, Tim MacMahon of ESPN.com reports.
Doncic will presumably have follow-up tests to determine the severity of the injury. Doncic has dealt with five separate incidents of lower body injuries since training camp, which adds up to be taxing from a muscular compensation standpoint on his kinetic chain. He was ruled out mere minutes after suffering the aggravation, which will thrust Spencer Dinwiddie into a higher-usage role for Dallas.
