Promotion from League Two remains the ultimate target for Northampton Town this season, those hopes boosted by Saturday's come-from-behind victory at Dagenham & Redbridge, but, with the Cobblers bandwagon rolling on and the carrot of a tie against Chelsea in the next round, Chris Wilder will be sending out his strongest possible side.
MK Dons will also fancy facing the reigning Premier League champions live on TV but their priority is remaining in the Championship and that may again dictate manager Karl Robinson's selection.
Joe Walsh boosted those hopes with a late winner to see off Reading on Saturday afternoon, the Dons now two points clear of the relegation zone and fully recovered from a 5-0 defeat by Burnley just four days previously.
Boss Robinson said afterwards: "We've got a mentality here that we stick together through thick and thin and it's about developing that here at the club."
