Kevin Manning faces a spell on the sidelines after breaking his collarbone in a fall at Galway.
The veteran Flat jockey suffered his injury when his mount Dublin Journal slipped up after a furlong in the Galway Handicap on Monday.
"He's broken his collarbone - but it's a straight-forward break, so it shouldn't be too long," said his agent Kevin O'Ryan.
"Thankfully, everything else is OK."
Manning, 54, has had a successful season - winning the 2000 Guineas and St James's Palace Stakes on Poetic Flare for his father-in-law Jim Bolger
