David Pipe has confirmed Conor O'Farrell will ride Our Father in this afternoon's Hennessy Gold Cup at Newbury.
Timmy Murphy was due to partner the seven-year-old but was taken to hospital for X-rays on his shoulder during racing at Newbury on Friday following a brawl with fellow jockey Dominic Elsworth in the weighing room.
Murphy had guided Upsilon Bleu to finish fourth in the bet365 Open Handicap Chase, a race where Elsworth and Easter Meteor filled the runner-up berth, before a heated altercation turned physical.
