England’s Rugby Football Union would need to approve the club relocation and change of name.
The governing body said it asked “repeatedly” for information required to enable Worcester to compete in the second tier.
“Deadlines were extended to provide the best possible chance for this to happen,” the RFU said.
Players and staff at Worcester — including Scotland star Duhan van der Merwe — had their contracts terminated amid its financial problems, with the club owing Britain’s tax authority about 6 million pounds ($6.8 million). Owners Colin Goldring and Jason Whittingham were accused of asset-stripping the Warriors.
Worcester’s men’s team had been in the Premiership since 2015. It won England’s Premiership Rugby Cup last season.
