Dante Exum will be out indefinitely with a broken bone in his left hand. Exum had become the starting point guard for the Dallas Mavericks following the season-ending injury to Kyrie Irving.
The Mavericks also recently lost Olivier-Maxence Prosper to a season-ending injury.
Furthermore, the return timelines for Anthony Davis, Dereck Lively II and Daniel Gafford are unclear.
Because the Mavericks are hard capped at the first apron after acquiring Klay Thompson via a sign-and-trade last offseason, they are cannot sign another player because even a 10-day contract would put them over.
