There are no “spares”. All tickets have the names of the person attending and will be checked.Is anyone attending the game or taking someone tomorrow on a 'spare ticket? Someone I know can't go and want to take my son. Seen all the stuff about health questionnaires and photo id, would you risk it?
You could chance it (you might get a lackadaisical steward) but you run the high risk of being turned away and the person who originally bought it also facing consequences
