Such players are designated as “Homegrown Player” on a club’s roster and count as domestic players, meaning they do not occupy an international roster slot on U.S. and Canadian club rosters not occupy an international roster slot. Clubs also have the option to designate a Homegrown Player as an Off-Roster Homegrown Player.
