Yorkshire's four-man Management Board were meeting at Headingley today to discuss what action to take over the death threat letter they have received following a dramatic slump in the team's form.

Chief executive Colin Graves said the contents of the signed letter would be assessed and a decision taken over whether to inform the police.

"Unfortunately, anything of this nature has to be taken seriously these days," said Graves.

The receiving of the death threat letter was revealed yesterday by the Board's director of cricket, Geoff Cope, who lives in Guiseley.

"We have not been playing to the best of our ability and quite a few supporters are not happy about it," said Cope.

"A death threat does cause concern but Yorkshire cricket is a very passionate part of life.

"The club was in a great mess last year and 24 hours from closure. What we have achieved since then is superb but there are disgruntled fans who feel that although the club is going the right way the players are not."

Yorkshire last week were heavily beaten by Worcestershire in the Cheltenham and Gloucester Tropy, which they won last year, and on Sunday they suffered their first ever Championship defeat by Durham.
