Colin's Sister is to seek Grade One glory at Fairyhouse's Easter Festival next month after a minor setback caused her to miss Cheltenham last week.A bruised foot forced the six-year-old to be a late withdrawal from the OLBG Mares' Hurdle over two and a half miles.However, Fergal O'Brien reports Colin's Sister to be back in light work and he will now prepare his Grade Two winner for the feature mares' novices' hurdle over the same distance at the County Meath track"She's a lot better. She was ridden on Monday. She'll canter for a couple of days and she's fine," said the Cheltenham trainer."We hope to go to Fairyhouse with her in the middle of April for a Grade One mares' novices' hurdle. Gordon Elliott and Willie Mullins will no doubt have a stack in here, but that's the plan at the minute."
