MHSAA plays by the rules published annually by the National Federation of State High School Associations. They publish notable rules information (differences, changes, etc), or you can order their book from them.
You can also go to the NCAA to get the NCAA mens lacrosse rules, either by ordering a paper copy or downloading the rulebook in PDF format for free.
The NFHS does not make their book available free online.
USLacrosse publishes an abridged version of men's rules (NCAA) and boys' rules (youth exceptions) on their website, but no longer maintains a list of differences between NFHS and NCAA.
Middle school plays by the NFHS rules with certain modifications as approved by MYLA.
If you have a question about a rule, application of a rule or a rule change, please send it to our MichLOA Rules Interpreter for an official answer MichLOARulesInterpreter@hughes.net
