Yorkshire chief executive Colin Graves is to meet up in South Africa with England and Wales Cricket Board chief executive Tim Lamb to discuss the potentially damaging consequences for county cricket of England refusing to play their World Cup match in Zimbabwe tomorrow.

Graves is anxious to get an update from Lamb on the serious financial implications of the escalating crisis.

As well as the ECB facing the prospect of having to foot a large compensation bill from the International Cricket Council for their stance, there is also talk that both Zimbabwe and South Africa may now refuse to visit England this summer.

And that would be a stunning blow for all of the counties, and particularly for Yorkshire, who are depending on the one-day international against Zimbabwe and the Test match with South Africa to pay back a large slice of the £5.6m they owe the bank for the redevelopment of Headingley.

Yorkshire - who will announce a £1m annual loss at next month's annual meeting - were only saved from bankruptcy last summer when a new four-man management board took over the running of the club.

"The £340,000 we will receive from staging agreements with the ECB for the matches is due to go straight to the bank, along with other money we will get out of the games," said Graves.

"We have already taken £250,000 in advance ticket sales for the Test match in August and £200,000 in hospitality packages.

"Yorkshire receive 54 per cent of their total income from the ECB and it would be very damaging if that were affected in any way through the ECB having less money to distribute.

"If Zimbabwe and South Africa do not come to England this summer it would be extremely serious and I think the ECB would have to try to find replacements."
