While we will no more in the coming days, expect Exum to be out through the start of the season and maybe much longer.

Sources inform Shams Charania of The Athletic that the veteran incurred what is being called "a serious right wrist injury," exact terms of which have yet to be divulged. Surgery may be needed to deal with the ailment, Charania adds. That said, Dallas is currently considering a variety of potential methods for dealing with the injury.
