Erik ten Hag's side do not yet know whom we will face on the road to Wembley, with a replay still be staged between Bristol City and Nottingham Forest.
That tie will be held at The City Ground next Wednesday (7 February), with extra-time and penalties if required to find a winner.
The away tie, our third on the trot in the competition this season, will kick off at 19:45 GMT and be shown live on BBC One, BBC iPlayer and BBC Sport.
The game is the Reds' reward for seeing off Wigan Athletic and Newport County in previous rounds.
