Pursuant to the Discovery Process, clubs may scout and sign players who are not yet under contract to MLS and who are not subject to another assignment mechanism (e.g., MLS SuperDraft). To sign a player through the Discovery Process, the club must first place the player on its Discovery List. A club may have up to five players on its Discovery List at any time and may remove or add players at any time. There is no limit to how many players a club can sign from its Discovery List. Expansion club San Diego FC may maintain seven Discovery List slots beginning January 1, 2024, through the 2025 Roster Compliance Date, at which point the number of slots will be reduced to five.
