The Linnets are expecting their biggest crowd since they were re-formed last year when they face St Neots in the fifth round of the FA Vase on Saturday.
The Linnets won promotion to Blue Square North by winning the Southern League last season and, despite a poor run of results in recent weeks, have accumulated enough points to avoid finishing in the bottom three.
Meanwhile, in the Hereward Teamware United Counties League Knockout Cup, the Linnets have been drawn at home to Daventry United or Bourne Town while in the reserve competition Lynn entertain St Neots, with the winners facing either AFC Kempston or Bugbrooke.
