Nina Carberry has not yet set a date for her return to the saddle after suffering a back injury in a fall at Clonmel last Thursday.
The leading amateur rider was due to partner star hunter chaser On The Fringe on his seasonal reappearance at Leopardstown on Saturday, but was forced to watch on from the sidelines after she was unseated from Strangford Lough.
With the Cheltenham Festival less than five weeks away, Carberry is keen to get back in the saddle as soon as possible.
She said: "I tore a ligament in my back and I don't know when I'll be back riding at this stage.
"It's not too bad and I'm having a bit of physio done.
"I'll get it looked at in another week and I should know more then."
