Cardiff have confirmed they paid £1m to Her Majesty's Revenue and Customs yesterday in part settlement of the club's unpaid tax bill.
The South Wales club are believed to owe in the region of £2.7m to HMRC and were yesterday handed a further 28 days to pay the remaining amount after their winding-up order was adjourned by the High Court in London.
Southend also had their winding-up order delayed in the High Court yesterday with the League One outfit owing £200,000.
Southend chairman Ron Martin claimed last month the club did not owe the money because they overpaid when it settled an outstanding £2.15m debt in November.
The club's lawyers wrote to HMRC last month to say they were "astounded" it had decided to proceed with a winding-up petition over a disputed debt.
