U's face Chairboys in early February.
Following discussions between the two clubs and the EFL, the game will now take place on Tuesday 7th February, as long as the Chairboys cup exploits allow.
Wycombe's involvement in the FA Cup saw the original game postponed last week and the new date is dependent on their FA Cup and Checkatrade Trophy involvement. The U's home game against Wycombe Wanderers has been rearranged.
Should they draw with Spurs in the FA Cup and require a replay, or beat Mansfield in the Checkatrade Trophy, another postponement of the U's league game will be required.
Any tickets purchased for the original date can be used for this rearranged fixture, or changed to another league game before February 7th.
