Berkhamsted at long last know their FA Vase fifth round opponents after Morpeth Town knocked out holders North Shields 2-0 on Monday night.
The Comrades welcome Morpeth to Broadwater on Saturday for a 3pm kick-off in a potentially season-defining clash.
Morpeth booked their trip to Berko despite conceding home advantage to North Shields, following several postponements at their own ground.
Morpeth have only lost two league games this season and currently sit third in the EBAC Northern League Division 1, which has provided five of the last six FA Vase winners.
On Saturday Berkhamsted are expecting their biggest crowd since the club was formed in 2009.
Home fans are urged to walk down to Boroadwater or use the town centre car parks and get to the ground early. Even with two turnstiles open, it is likely to be very busy, so if people have the right change it would be helpful. Admission is £6, with seniors only £3 and no charge for accompanied young children.
Local businesses have rallied to the Comrades’ cause, with eight firms sponsoring the match.
If the scores are level after 90 minutes, there will be 30 minutes of extra-time played.
