Exum sustained a right wrist injury during training camp that could require surgery, Shams Charania of The Athletic reports.
Treatment options are being evaluated for Exum, though he could miss a significant amount of time due to the injury. The 29-year-old typically served as a spark off the bench last season, during which he averaged 7.8 points, 2.9 assists and 2.7 rebounds across 19.8 minutes per game in 55 regular-season appearances (17 starts). Exum could miss substantial time, and if he does Naji Marshall, Jaden Hardy and Quentin Grimes are candidates for extra minutes.
