Diss Rugby Club are expecting a bumper crowd at Mackenders a week on Saturday (April 25) after being drawn at home to north-west London outfit Chiswick for a straight play-off for a spot in London One North.
The Blues earned the home advantage (with a 3pm kick-off) courtesy of a better average points scored than the runners-up of London Two North West.
Diss concluded their regular season in London Two North East with a 44-14 home victory over Basildon on Saturday.
It was only five years ago that both Diss and Chiswick were in National League Three London and South East together.
If successful, Diss will joint old rivals North Walsham in London One North.
The play-off match will be preceded by the traditional club lunch which starts at 12:30pm with a maximum of 200 places available on a first-come first-served basis.
To pre-book for the lunch, contact Steve on 07850 320660 or David on 07831 881093.
