Overall, the National Federation of State High School Associations (NFHS) Boys Lacrosse Rules Committee adopted or clarified 15 boys lacrosse rules and officials signals at their summer meeting in Indianapolis. These are the highlights of the fifteen changes. You can read the complete 2018 NFHS rules change memo here.
Rule 1-2 offers schools a third potential field layout; a unified boys and girls field that allows schools to line one set of shared boys and girls lacrosse field markings. This field option is 120 yards long and include additional space in front of the goal for the boys. In the past, this was a 20-yard space between the restraining line and the goal but is now a 25-yard space.
Rule 1-7-5 allows crosse pockets of manufactured nontraditional synthetic material.
Rule 1-9-1g (8) better defines home and away jerseys.
Rules 4-3-3d states that during faceoffs the reverse surfaces of crosses must match evenly so that the top of one head lines up with the throat of the other and they are perpendicular to the ground. GLOA trainers began to introduce this mechanic last spring. The expression “tip to stop” provides a good visual.
Rule 4-3-3n now specifically states the circumference of the shaft shall not exceed 3.5 inches, and a contrasting color between the head and the top glove must be visible on the shaft during faceoffs (it may be tape or paint).
Rule 4-9-2o states a goal will be allowed if a shot is released prior to the end of a period. This is an adoption of the NCAA rule.
Rule 6-5-2x The rule further clarified proper mouthpiece usage; it is a penalty if a mouthpiece is not properly worn inside a player’s mouth. No “fish-hooking.”
