DORCHESTER Town, Weymouth and Bridport have seen their respective matches against Tiverton Town and Truro City postponed due to waterlogged pitches.
Tiverton's Ladysmead ground is saturated and the fixture has been postponed for a third time.
The Magpies are currently on a four-game unbeaten streak and were looking to extend the gap to 20th-placed Tivvy to 10 points.
However, the rain has once more intervened and the two clubs must find a new date to attempt to complete the fixture.

Tom Killick’s men still have 10 matches of the Pitching In Southern League Premier South season to play before the scheduled finale on Saturday, April 27.
Dorchester are next in action at Beaconsfield Town on Saturday (3pm).
Meanwhile, Weymouth's match against Truro City was scheduled to take place at Taunton Town.
Nomadic club Truro have been forced into playing their home matches away from Cornwall this season, their latest agreement struck with Taunton.
However, the Peacocks’ Wordsworth Drive home has been awash with postponements this season, adding the newest call-off to the list.
Truro have also been playing home matches at Gloucester City’s 3G pitch and it remains possible the fixture could move to that location, should Truro and Weymouth find agreement.
However, Weymouth are understood to prefer Taunton if the weather relents.
The Terras are next in action at home to Braintree on Saturday (3pm).
Meanwhile, Bridport were scheduled to play Okehampton at the neutral venue of Cullompton in their Walter C Parson Cup semi-final.
However, a local referee assessed the pitch as unplayable during a lunchtime inspection.
The tie has been rescheduled for Tuesday, March 26, with Bridport's next game coming at home to Torridgeside on Saturday (3pm).
