A new date has been arranged for Pompey’s League One visit to Luton.
The promotion rivals were due to meet next weekend, but the contest was postponed after both sides reached the third round of the FA Cup.
Kenny Jackett’s side will now make the trip to Kenilworth Road on Tuesday, January 29 (7.45pm kick-off).
Fans should note that this new date is subject to neither side having an FA Cup fourth round match on the preceding Sunday or Monday.
Ticket information for the game will be announced in due course.
