Durham's Twenty20 quarter-final with Yorkshire was remarkably postponed after Tykes spinner Azeem Rafiq was alleged to be an ineligible player. Spectators were gathered at the Riverside ready for the 1740 BST start when the news filtered through. The England and Wales Cricket Board is investigating the matter and asked that the match be played at a later date. Rafiq, 17, made his Yorkshire debut in their final group match against Notts, which a panel may order to be replayed. Both teams were preparing for Monday's quarter-final, unaware of what was to follow until little more than an hour before the scheduled start

Essex dominated Yorkshire with both bat and ball at Chelmsford to claim a 87-run victory that books their place in the Friends Provident Trophy final. England opener Alastair Cook hit a fine 95 and Graham Napier struck 61 off 34 balls as the hosts finished on 285-8. Andrew Gale (64) and Anthony McGrath (53) offered Yorkshire early hope before they collapsed to 198 all out.
