However, the club was determined the musical fireworks extravaganza would go ahead and made the decision that the spectacular - themed 'A Night at the Movies' - would take place this Friday.
Gates will open at 6pm - the show starts at 8pm - with visitors to Sixways treated to £10,000 worth of fireworks choreographed to music from children's favourite movies.
There will also be a live band on site, bars open across the complex and fast food available. Covered seats will be available to make comfortable viewing and there will be free limited parking on site.
"We pride ourselves on having one of the best firework displays in the county and with £10,000 worth of fireworks ready to be let off into the night sky to a stunning musical backdrop we're confident that this year's show will still be the best ever," said Charlie Little, Warriors General Manager.
"We feel this event is now the perfect way to start the weekend and I would urge families to come along and enjoy an unforgettable night under the stars with Worcester Warriors."
Stadium Tickets will be available on the night at £6 for adults and £3 for juniors. Advance prices are £5 an adult and £2.50 a junior. Call the Ticket Office on 0870 990 5650 for more details. All tickets purchased for Sunday's show are valid for the rearranged date.
