Vaughan misses C&G quarter-final
Michael Vaughan will miss Yorkshire's C&G Trophy quarter-final, against Northamptonshire on Saturday, to ensure the groin injury he suffered during the NatWest Series does not occur again.
The ECB's chief medical officer, Dr Peter Gregory, said: "We need to ensure that there is no further deterioration to the groin strain that kept Michael out of two matches. We are confident, however, that with rest Michael will be fully fit for the first Ashes Test at Lord's next week."
The remaining centrally contracted players are available for the counties who are involved in the quarter-finals. This means that Andrew Flintoff, Ashley Giles and Geraint Jones will be making rare county appearances while Matthew Hoggard is available for Yorkshire.
Graham Thorpe is also available for Surrey, although his Test position will be known by the time they play Hampshire as the squad is named on Thursday.
