Millwall have been drawn at home to Bristol City in the Emirates FA Cup Fourth Round.
The two sides will meet in an all-Championship affair for a place in Round Five after being picked out together in Monday night's draw.
Should The Lions advance to the Fifth Round, then they will travel to either Sheffield United or Plymouth Argyle.
As a result of Millwall's progression into Round Four, the Sky Bet Championship home fixture against Norwich City will be rearranged. A new date and kick-off time will be confirmed in due course.
