Ollie Magern Out Of Grand National Ollie Magern will miss Saturday´s John Smith´s Grand National and instead run in tomorrow´s #150,000 Betfair Bowl at Aintree.Trainer Nigel Twiston-Davies said: 'Owner Roger Nicholls thought that Ollie Magern would be better suited by the Betfair Bowl which has got terrific prize money and will have a smaller field.'This means that jockey Carl Llewellyn will switch to Baron Windrush, also trained by Twiston-Davies, in the John Smith´s Grand National.
