Rick Carlisle revealed on Monday night that the Mavericks have decided to add veteran guard Darrell Armstrong to their coaching staff.

Carlisle coached Armstrong while with the Pacers and has remained in touch as Armstrong finished his playing career.

Armstrong will make his retirement official with the league in the near future. He played 50 games last season with New Jersey.
