Somerset's Vitality Blast quarter-final against Nottinghamshire will be held over until Bank Holiday Monday due to inclement weather at Taunton.
The Finals Day line-up was scheduled to be completed on Sunday, with Lancashire, Sussex and Worcestershire having already booked their places at Edgbaston on September 15.
But persistent rain in the south west forced an abandonment to the final last-eight tie.
Better weather is forecast for Monday and a start time of 1pm has been scheduled.
