Tony Dobbin, Mick Fitzgerald and Barry Geraghty will all have to pass doctor's tests before riding in Saturday's John Smith's Grand National after the riders were injured at Aintree on Friday.

Geraghty soon had an ice pack on his left hand after a heavy fall from Mister Top Notch in the handicap chase. But the rider of leading National fancy Slim Pickings insisted: "I'll be absolutely fine for tomorrow."

Fitzgerald, who hit the ground riding Crozan at Becher's Brook in the Topham Chase, was similarly adamant that he will team up with L'Ami on Saturday afternoon.

Tony Dobbin - who also today announced that he will retire on Thursday - will "hopefully" have his last National ride on Point Barrow.

Dobbin, left battered and bruised by the fall of Nacarat in the Topham, said: "I got a bit of akicking and my shoulders and chest are quite sore, but this is my last chance in the National, so I want to ride."
