Ruby Walsh to miss Grand National after sustaining fractured wrist

Ruby Walsh will miss tomorrow's Crabbie's Grand National meeting after suffering a wrist injury in a fall at Aintree.

The jockey was due to partner the Willie Mullins-trained Sir Des Champs in a bid to win the world's most famous steeplechase for a third time and in his absence leading female amateur Nina Carberry will come in for the ride.
