Stephen Walker scored either side of the break as Dons deservedly sealed their spot in the last eight of the competition. Here are our player ratings...
9. Ryan Watson
A key part of his role in the side is to link midfield with attack but he couldn't do that effectively against Dons and as a result Cobblers struggled to build any forward momentum... 5
11. Benny Ashley-Seal
Disappointing display following a couple of excellent recent showings. His hold-up play was lacking as Dons kept him in check throughout the evening... 4.5
12. Ricky Korboa
On at half-time and wasted Town's best chance of the night, shooting straight at Nicholls after the ball had fallen kindly to him... 5.5
