With the announcement that Dante Exum will be out for at least three months after needing surgery on his wrist, the Dallas Mavericks will have to replace the minutes he had been giving them as a backup point guard on the roster who typically comes in to replace either Luka Doncic or Kyrie Irving as the lead initiator.

The Mavericks announced Wednesday that Dante Exum underwent successful surgery on Tuesday to repair a right wrist injury sustained in training camp. The team did not offer a timetable for his return, but ESPN’s Shams Charania reported that Exum is expected to miss three months — a blow to Dallas’ backcourt depth.
