The new reserve list category was created for a player who either tests positive for COVID-19 or who is quarantined after being in close contact with an infected person. If a player falls into either of these categories, their club is required immediately to place the player on the reserve/COVID-19 list.
Clubs are not allowed to disclose whether a player is in quarantine or is positive for COVID-19.
