Spurs were held to a 2-2 draw at Rochdale in Sunday's fifth-round tie, which means a replay at Wembley Stadium for the right to face Sheffield Wednesday or Swansea City in the quarter-finals.
Due to both clubs' packed schedules, with Spurs in the Champions League and Dale having a high number of games in hand in League One, the replay has been provisionally scheduled for Wednesday, February 28.
Tottenham's trip to Selhurst Park was initially scheduled for 8pm on Monday, February 26, but Sky Sports News has announced that this has now been moved to Sunday, February 25 at 12pm.
Palace have confirmed that tickets purchased for the original Monday night match will still be valid for the fixture, while the game remains live on Sky Sports.
Tottenham have been taken to a replay in back-to-back rounds in the FA Cup for the first time since 2009-10.
