The Magpies second string had been due to welcome Brighton to Whitley Park on Monday, 9th January, for a 7pm kick-off.
But the game has been brought forward by two days due to the Seagulls' participation in the Checkatrade Trophy on Tuesday, 10th January, and will now be played at United's Little Benton Academy on Saturday, 7th January, with kick-off set for 12 noon.
