Dallas Mavericks guard Dante Exum sustained an injury to his right wrist during training camp, the team announced on Friday, and The Athletic's Shams Charania reports that treatment options are being evaluated with surgery a possibility.

The Mavericks announced the right wrist injury, but it was Shams Charania of The Athletic who filled in the details that this is a “serious” wrist injury that could require surgery. While we will no more in the coming days, expect Exum to be out through the start of the season and maybe much longer.
