MK Dons claimed the chance to meet Chelsea, live on the BBC, in Round 4 after a controversial replay on Tuesday evening in which the hosts were the beneficiaries of two penalties.
Chris Wilder's side matched their Championship opponents over 180 minutes of football but have the huge incentive of bouncing back quickly in the knowledge that a win over Morecambe at Sixfields on Saturday could put them top of League Two.
With around 7,000 Town fans having made the trip to Stadium:MK, the club are hoping to pack the home stands this weekend.
Wilder told the official NTFC website: "We have to move on quickly, we’ve got a massive game against Morecambe on Saturday and I’d love to see another sell out."
