Warwickshire's Cheltenham & Gloucester Trophy clash against Yorkshire was abandoned after four overs because of rain at Headingley.
Bears skipper Heath Streak won the toss and put the hosts into bat in the North Conference fixture but play was possible for only 15 minutes.
Matthew Wood and skipper Craig White had taken the score to 14 without loss when the match was abandoned.
After Saturday's starring role at The Oval, Worcestershire's Phil Jaques had to put his home debut on hold.
The Australian opener was forced to sit in the New Road pavilion as his new county's C&G Trophy clash with Durham was rained off.
A week of rain in Worcestershire had already left yesterday's match in severe doubt. But a morning's persistent downpour left puddles on the pitch at the New Road end and led to the match being called off just after one o'clock.
The county are hoping for an improved forecast to ensure that their saturated playing surface dries out in time for their next match, tomorrow's County Championship clash against Glamorgan, when Jaques will make a delayed first home start.
Worcestershire are also hopeful that they might by then have had a more encouraging injury bulletin on fast bowler Matt Mason, who suffered a groin injury in the win over Surrey at the Oval.
