Caithness suffered a day to forget as they went down 114-0 at Ardrossan Academicals.
The Greens went into the match on a positive note following a 29-20 victory against Perthshire the following weekend. But Caithness head coach Ewen Boyd made the trip to Ayrshire with a depleted squad – 19 regular starters were unavailable, including Evan Sutherland and Marc Anderson who are both sidelined until February.
It was always going to be a tall order against one of the leading teams in National 3 and Ardrossan proved far too strong.
Boyd said: “We lost heavily and it was a hard result to take.
“We are in a transitional phase at the minute so young and inexperienced players will get game time in high-pressure games.
“Unfortunately it was one of those games where Ardrossan were on fire.”
The result leaves Caithness sitting second bottom, five points above bottom of the league Carrick who have lost all nine games this term.
The Greens host Carrick on Saturday.
In the only other game to survive the wintry weather, Greenock Wanderers defeated Perthshire 49-24 to stay top of the league.
Gordonians were denied the chance to return to winning ways when their National 2 showdown with Peebles was postponed due to a frozen pitch.
All six games in National 2 were called off due to the weather.
Gordonians, who remain second bottom, host Preston Lodge on Saturday before travelling to Dumfries Saints on December 14 in their final match before the break.
