Ashes skippers to face media
Alastair Cook will face the media today as the build-up to the fourth Ashes Test continues to be dominated by rows over the Decision Review System.
Kevin Pietersen reacted furiously on Wednesday to claims both England and Australia were under investigation by the International Cricket Council for allegedly attempting to cheat the Hot Spot system.
The allegation - that players were applying silicon to their bats to conceal contact with the ball - originated from an item on an Australian television channel, and the England and Wales Cricket Board has reportedly asked for an apology.
The ICC quickly rubbished suggestions of an investigation and said its director of operations Geoff Allardice had been dispatched to England for no other reason than to discuss the general use of DRS.
Both teams have expressed concern over the umpires' interpretation of the system during the first three Tests, and Allardice's brief is to run through the best way of using the technology.
In the meantime Cook and counterpart Michael Clarke are preparing for Friday's first day at Durham with the destination of the Ashes already decided following the drawn third Test at Old Trafford.
England's aim now is to win the urn outright rather than just to retain it, and Graham Onions could come into contention for a recall on his home ground if Cook and Andy Flower decide to make changes.
Both skippers will give press conferences on Thursday, and you can keep up to date with all the latest news on Sky Sports News and via the mobile and iPad apps.
