Since 2019, the IBLA has served as an official partner of the National Lacrosse League, serving as a developmental funnel. The league was founded in 2017 to unite regional semi-professional leagues into a system similar to the Canadian Lacrosse Association structure of men's Senior A and Senior B indoor lacrosse teams. As of 2020 there are 32 total teams playing in 11 regional leagues. The Maine Northmen are the most recent IBLA champions, defeating the Louisville Canards in Huntington Beach, California.
