The Seasiders will head into the fixture with a spring in their step following back-to-back 4-0 wins against both Shrewsbury Town and Portsmouth.
Owen Dale, Jake Beesley, CJ Hamilton and Albie Morgan were all on the scoresheet at Fratton Park on Saturday afternoon.
Discussing his squad options ahead of tonight’s game, Blackpool boss Neil Critchley said: “It’s pretty much as you were to be honest. Shayne (Lavery) and Kylian (Kouassi) are out for a number of weeks.
"Ollie Norburn was touch and go for Saturday- and did a little bit of training at the back end of last week, so I’m sure he’ll put himself up for selection and we’ll have to make a decision on him.
"As far as I know, we didn’t suffer any injuries on Saturday.”
Here’s our predicted Seasiders XI for the visit of Northampton:
19. SUB: Jake Beesley
Jake Beesley has enjoyed a great run of form, with five goals in his last three games in all competitions. The striker could perhaps be given a little breather ahead of the cup game at the weekend, but it will be a close call. Photo: CameraSport - David Horton
