Ruby Walsh will miss the Punchestown Festival after breaking his arm in a fall at Aintree on Satu day.

Walsh suffered a crashing fall from the Paul Nicholls-trained Celestial Halo in the Aintree Hurdle and after being thrown to the ground, he was then kicked by Won In The Dark.

The Irish champion jockey was forced to miss the ride on Grand National joint-favourite Big Fella Thanks, who went on to finish fourth behind the Tony McCoy-ridden Don't Push It, and now Walsh is set for an uncertain spell on the sidelines.

The jockey's sister and agent Jennifer Walsh said on Sunday: "He arrived home last night but we're not sure how long he's going to be out for yet.

"He's going to miss Punchestown but he's going to see his own orthopaedic surgeon on Monday morning and we'll know an awful lot more then.

"I think Ruby got to speak to AP (McCoy) before he came home last night and he's delighted for him."
