Yorkshire will be taking extra measures to try to ensure that spectators who come on to the field at the end of Sunday's Super Six World Cup match at Headingley between Zimbabwe and New Zealand do so in an orderly manner.

They want to try to avoid a repeat of the scenes when the ground was invaded after Australia's game with Pakistan on May 23.

"Someone sooner or later is going to break an arm or a leg if they keep charging on," said Yorkshire chief executive Chris Hassell.

"It is very difficult to stop people coming on, but we will have extra stewards around the perimeter near the close to try to stem the flow, and we will also make announcements on the public address system asking people to take care."

About 2,000 tickets are still available for the match, and these can be bought either by credit card or by paying at the gate. Prices are £60 or £36.

David Graveney today pinpointed the drawn-out contract talks as a contributory factor in England's disappointing early exit from the World Cup.

Chairman of selectors Graveney was at the centre of the talks, having acted as a mediator between the 15-man squad and the England and Wales Cricket Board - discussions which undermined preparations both during the training camp in Lahore and at the Coca-Cola Cup in Sharjah in April.

But as England are forced to settle for a watching brief as the Super Sixes stage of the tournament begins with India facing Australia at The Oval tomorrow, Graveney claimed the protracted negotiations inflicted irreparable damage on their campaign.

"I think it stems back to a particular incident back in Sharjah - this rather unseemly dispute about contracts and the money involved with the players which unfortunately started the campaign for the World Cup on the wrong foot," said Graveney.

"That was a factor - it could have been handled in a far better way. "
