Del Harris is expected to sign as an assistant coach with the Chicago Bulls today, ending his nine year tenure with the Dallas Mavericks, the Dallas Morning News is reporting.

Harris joined the Mavericks in 2000 and was top assistant to Don Nelson until Nelson gave over the coaching reins to Avery Johnson in 2005. Harris served as a consultant last season.

New Mavericks' Coach Rick Carlisle has already signed Dwane Casey and Terry Stotts as assistants and likely will have Mario Elie and one other coach on the staff.
