Jockey Brian Toomey remains in a "stable condition" after undergoing surgery on the serious injuries he sustained in a heavy fall at Perth last Thursday.
The 3lb claimer is still in an induced coma at the Ninewells Hospital in Dundee after the surgery which was undertaken to reduce swelling and pressure on his brain.
He was injured in a fall from the Lisa Harrison-trained Solway Dandy in the Book Now For 2014 Perth Festival Conditional Jockeys' Handicap Hurdle.
A statement from Lisa Hancock, CEO of the Injured Jockeys Fund, on behalf of the Toomey family and the Professional Jockeys Association read: "Brian Toomey underwent surgery yesterday (Sunday) to reduce swelling and resultant pressure on his brain.
"The surgery went well and Brian remains in a stable condition in an induced coma. It is anticipated he will be kept sedated for the next few days as his progress continues to be monitored."
The statement added: "Brian's parents Marian and Johnny, brother Sean, sister Aine and his aunt Margaret would like to thank all family and friends at home in Ireland for their huge support.
"Mrs Toomey would also particularly like to thank Dr Michael Turner for travelling up to Dundee on Saturday and the staff at Ninewells Hospital for their fantastic round the clock care.
"Brian's girlfriend Amy Ryan would like to thank all family and friends and the racing fraternity for their texts and phone calls, especially Brian's close friends Brian Hughes and JP O'Farrell.
"Kevin Ryan (trainer and Ryan's father) would also like to thank his owners and staff for their support over the last few days."
