Ground key to Nicholls stars’ Exeter workout

Trainer Paul Nicholls is keen to work the pair, who are set to contest the Ladbrokes World Hurdle and Betfred Cheltenham Gold Cup respectively next month.
Four-times World Hurdle winner Big Buck’s returned to action after a lengthy lay-off with a close third in the Cleeve Hurdle last month, while Silviniaco Conti was last sighted when winning the King George at Kempton on St Stephen’s Day.
