Barnet's home clash against Portsmouth has been rescheduled for Tuesday, February 23.
The game had to be moved from the original date of January 30 after Pompey beat Ipswich in their FA Cup third round replay to set up a home tie in round four against Bournemouth.
It will now kick off at 7.45pm.
Pompey currently sit fifth in League Two, four points shy of the automatic promotion places.
