Solwhit will miss the defence of his Ladbrokes World Hurdle crown through injury according to trainer Charles Byrnes.

Byrnes has drawn stumps with the luckless 10-year-old after a fetlock problem which prevented him from making his reappearance at Leopardstown over Christmas failed to show the required improvement.

Big Buck's, who has not raced since December 2012, is now a warm order to rack up his fifth win in the race.
