Kris Dunn cannot be traded to a team aggregated with other players from his team because 19 days have not passed since he was traded for (Normally 2 months, but shorter due to condensed season). He can only be traded away to a team by himself and other non-player assets from his team (draft picks, cash considerations, etc). This restriction expires after Aug 26, 2021.

Kris Dunn currently has a player option for the Celtics this season. He may decide to decline his option and sign with another team. You may accept or decline this option, by default it will be accepted. You may also update his contract to perform actions such as a Sign & Trade.
