London 1 North relegated side Diss fail to score a point during defeat at Ruislip
It is now 10 London 1 North defeats in a row for relegated Diss, who failed to trouble the scoreboard for the fourth time this season in their 55-0 loss at Ruislip on Saturday.
The long-suffering Blues, who have been rooted to the foot of the table for the majority of the campaign, found themselves 33 points down heading into the break.
And the gap widened even further after the restart, with their 11th-placed hosts easing to victory to put four points between themselves and Fullerians in the final drop zone position.
For Diss – relegated some weeks ago – they now have one game left to play of a season that has seen them triumph just once (a 40-19 win over Luton on January 5).
However, it would appear they have their work cut out to end on a winning note, with the visitors to Mackenders being a second-placed Colchester side that has lost just twice this term (3pm).
It will also mark a last league game in charge for head coach Dave Smith, who is to step aside and be replaced by former North Walsham, Ipswich and Southend Saxons chief Nick Greenhall ahead of the 2019/20 season getting under way.
When Diss headed to Colchester on the opening weekend of the season, the hosts ran out victors by a 55-5 margin. Finding themselves 31-0 as the half-time whistle was blown, Diss’ consolation try was scored in the second half by Shaun Blyth.
The Blues will have one more game after the clash against Colchester, with Holt set to visit on Saturday, April 20 for the annual Harrison Cup.
