Per Kevin O'Connor of The Ringer, citing a front office source, Butler is "as good as gone" from Chicago after this season.
Adrian Wojnarowski of The Vertical reported last month the Bulls ownership and front office needed to get on the same page to determine if a full-scale rebuild was necessary, adding the Boston Celtics made for a potential fit for Butler because of their future draft assets.
While nothing materialized at that time, Butler's career with the Bulls could be coming to an abrupt end. They are on the verge of missing the playoffs for the second straight season and lack depth behind Butler on the roster.
Butler would also seem to be a valuable trade asset this summer because of his contract . He's signed for the next two seasons for a total of $36.2 million with a player option for 2019-2020, per Spotrac.
