Rico Doubtful From O'Brien Quartet Aidan O'Brien revealed that a 'slight doubt' has arisen over Puerto Rico's participation in the Ladbrokes St Leger on Saturday.O'Brien was responsible for four of the 12 horses at Monday's acceptor stage for the final domestic Classic of the season at York.And while Tusculum, Fire And Rain and Mountain look set to take their chance, a decision on Puerto Rico is not likely to be made until Wednesday.'As things stand, we are planning to run Tusculum, Fire And Rain and Mountain but there is a slight doubt about Puerto Rico as he has had a bit of trouble with a stone-bruise and has missed a few days cantering,' said O'Brien, who has won three of the last five renewals of the St Leger.'We'll decide about him on Wednesday.'The Ballydoyle handler also confirmed that experienced jockey Kevin Darley, who won the St Leger aboard Tim Easterby's Bollin Eric in 2002, will be riding for his yard in the one-mile-six-furlong contest on the Knavesmire.'We have booked Kevin to ride for us in the St Leger but it will be a day or two before we finalise running and riding plans for the race,' O'Brien told the Racing Post.?
