The Eagle Challenge Series is a traditionally-minded, highly competitive box lacrosse event series. The overall aim of both Eagle Box and the Eagle Challenge Series is to promote more rapid, U.S. growth in the most skill-driven and physical form of our sport, Box Lacrosse. The Men’s (Senior) series features 6 teams per event and serves as developmental platform for some of the highest level, non-professional box lacrosse players in the United States. Following suit with the Men’s event rules and competitive standard, the High School and Youth events include moving picks and “educated cross-checking” to allow younger U.S. lacrosse participants to engage in the Canadian box game. Bicep guards and box rib pads are required at all levels of play.
