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.
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.
