Racing:Ruby Walsh will be out for at least two months as he recovers from a broken arm sustained from a fall in Saturday's Aintree Hurdle.
The leading jockey was taken to hospital after Celestial Halo crashed out, at which stage he was then kicked by Won In The Dark.
He missed riding Big Fella Thanks in the Grand National and returned home to Ireland that evening.
Walsh went to see his orthopaedic surgeon this morning and his sister and agent Jennifer said: "He went to see (surgeon) Bill Quinlan this morning. The arm is in plaster and he is going to be out for eight to 10 weeks."
Paddy Flood is also set for a spell on the sidelines after a tumble at Aintree. He broke his collarbone when Schindlers Hunt suffered a fatal fall in the John Smith's Melling Chase, causing him to miss the ride on Vic Venturi in the National.
His agent Ciaran O'Toole said: "I haven't heard of any further complications apart from the collarbone. It was just a shame for him, with Aintree and then Punchestown round the corner. Sometimes they can be back in three weeks, sometimes it takes a bit longer."
