The 2017–18 Chicago Bulls season was the 52nd season of the franchise in the National Basketball Association (NBA). For the first time since 2011, All-Star Jimmy Butler was not on the roster as he was traded to the Minnesota Timberwolves in the off-season. On February 1, 2018, months after his confrontation with teammate Bobby Portis, Nikola Mirotić agreed to a trade where he'd be sent alongside a future second round pick to the New Orleans Pelicans in exchange for Ömer Aşık, Tony Allen, Jameer Nelson, and a future first round pick. The Bulls had their first losing season since 2008, and their first 50-loss season since 2004.
