Is the use of the dash correct in the following sentence?
"These rules fall into three categories: first, the rules according to which a sport is played, i.e. “the rules of the game”—autonomy is most extensive in this area; second, the rules governing the game off the playing field, such as nationality clauses and player transfer rules; and third, general association rules concerning, for example, internal procedures and organisation."
Thanks a lot.
