Diss kept up their winning start to the season as a late try two minutes from time helped them to a hard-fought 28-22 win over local rivals Ipswich.
Hosts Ipswich raced into leads of 11-0 and 22-14 during the early season derby, but with five minutes to go Steve Hipwell’s try, converted by Sean McClure closed the deficit for Diss to one point.
Diss were awarded a penalty on 78 minutes and made the brave call to scrum, and it proved to be the right one as McClure converted the try to seal a dramatic victory.
The Mackenders outfit are top of London Two North East with two wins from their opening two games of the season.
