Kielan Woods is facing a spell on the sidelines after breaking his pelvis in a fall at Huntingdon on Monday.
The rider parted company with Bare Necessities at the second flight in a two-mile hurdle at the track, suffering a break in the course of his tumble.
Woods tweeted: "Unfortunately I broke my pelvis yesterday. Absolutely gutted, but it could be a lot worse. Thanks very much for the (get) well messages!"
