After a 0-0 draw at Sixfields ten days earlier, the two sides will battle it out again – with a second round trip to face Doncaster Rovers at the Keepmoat Stadium awaiting the victors.
It will be the second of three matches against the Cobblers in the space of a fortnight, with United taking them at Sixfields again in the league on Saturday.
TEAM NEWS…
Iron manager Graham Alexander says Josh Morris will be assessed, after coming off at half-time of the win against Bristol Rovers on Saturday due to a hamstring injury.
Fellow midfielder Andrew Crofts won’t be available though, after being called up for international duty by Wales.
However, defender/skipper Rory McArdle is back with the club after being on international duty with Northern Ireland and will be looked at by the coaching staff before a decision is made on his involvement.
Conor Townsend has had a full week of training following his hamstring injury, while Sam Mantom (groin), Luke Williams (hamstring) and Jonathon Margetts (knee) will continue to miss out.
LAST TIME OUT…
We drew 0-0 away at Northampton in the initial tie ten days ago. It was a game of few chances, but Scunthorpe almost won it late on when Cameron Burgess headed wide in the closing stages.

ONE TO WATCH…
Midfielder Matt Grimes, who is on loan from Swansea City, is one to watch for Northampton. He scored a stunning free-kick last month against Gillingham and has three assists in League One.
The 22-year-old moved from his hometown club Exeter City to the Welsh club for a figure believed to be in the region of £1.75-million.
He has since spent time on loan in the Championship with Leeds United and Blackburn Rovers.
