The second round match was originally due to take place the following Tuesday but, with both teams out of the FA Cup, the decision has been made to move it to the Saturday.
Tickets for the game have been reduced to £10 for adults and £5 for seniors (63 and over) with juniors 17 and under getting in for just £1.
The Cobblers reached the second round stage after a dramatic 3-3 draw with Southampton U21s in their final group match earlier this month.
