The winners of the Hitchin v Clevedon game on Tuesday night will meet either AFC Hornchurch or Welling United in the FA Cup fourth qualifying round on October 28.
Hitchin have never met Conference South club Welling, but Hornchurch are the latest reincarnation of the club that Hitchin last played against in 2003-04.
If Hornchurch win through it will bring the Canaries face to face with former favourite Adam Parker.
Welling meet AFC Hornchurch 24 hours after Hitchin play Clevedon at Top Field.
