Stage 19 of the Rally of Turkey has also been cancelled due to poor stage conditions following heavy overnight rain.
The organisers had earlier called off SS18, and have now decided that the morning's scheduled second stage cannot be used either.
The overnight weather has left the stages extremely wet and muddy, with reports from the scene suggesting that while the conditions were acceptable for rally competitors, it would not be possible to get safety crews' vehicles through the mud.
Both the Deniz and Mudarli stages are currently due to run again after service. The cancellation of their first runs has already reduced the final day mileage by 37 kilometres, and given Petter Solberg and Mikko Hirvonen far less time to chase down leader Sebastien Loeb, who holds a 16-second advantage but is running first on the road.
The expectation is that SS20 Ballica - the final stage of the opening loop - will run as planned at 10.39am local time.
