The TMO will have 8 minutes to either uphold a 10-minute Yellow Card decision or upgrade it to a 20-minute Red Card, in which case the player will not return to the field, but can still be replaced. Basically the same as the orange card concept.
Referees will now also have the power to issue a full Red Card for deliberate foul play, in which case the player will not return to the field and cannot be replaced.
