The Magpies progressed to the last 16 of the competition for the first time since 2006 following a dramatic extra-time victory against Oxford United on Tuesday night.
As of this season, Fifth Round ties no longer take place over a weekend and will instead be played midweek. There will also be no replays, with all games heading to extra time and, if necessary, penalties to determine which side goes through in the event of a draw.
West Brom – now managed by former West Ham boss Slaven Bilic – are currently top of the Championship as they bid to return to the top flight after a two-year absence. The Magpies drew 2-2 on their last visit to the Hawthorns midway through the 2017/18 campaign.
Please note that the game will not be televised. Ticket information will be confirmed in due course.
