Rock to miss York Multiple Group One winner Rock Of Gibraltar is set to miss York's Ebor Meeting, it emerged today.The Aidan O'Brien-trained colt, who carries the colours of Manchester United boss Sir Alex Ferguson, equalled Mill Reef's record of six consecutive victories at the highest level when he won the Sussex Stakes at Goodwood last week and had Group One options at York in the Victor Chandler Nunthorpe Stakes and the Juddmonte International Stakes.However, several of O'Brien's Classic generation have been affected by coughing and the Ballydoyle trainer told the Racing Post: 'York is now off the agenda for Rock Of Gibraltar, who is on a break together with many of the other three-year-olds.'
