The clash with Fulham at Craven Cottage moves from Easter Monday to the following evening, Tuesday, April 19, with a 7.45pm kick-off.
That switch has been done by agreement between PNE and the Cottagers.
There were no trains running to London on the West Coast line over the Easter weekend which would have made travel difficult.
The second switch is the derby with Blackburn Rovers at Deepdale, initially scheduled for Saturday, April 23.
It has been moved to Monday, April 25, and will he shown live on Sky Sports. Kick-off is 7.30pm.
More notice is usually given to move games for television coverage, however a shorter notice spell seems to be allowed towards the end of the season when games could have a bearing on promotion, play-off places or relegation.
