Jockey Paul Carberry has proved his fitness and will ride Champion Hurdle hope Harchibald in Tuesday's Cheltenham showpiece.
Carberry, who is also due to team up with Beef Or Salmon in Friday's Gold Cup, satisfied doctors he was fit after complaining of sore ribs on Sunday.
The jockey returned from injury at Naas at the weekend and reported himself in pain after winning the two-mile novice hurdle on Arteea.
He was immediately stood down by Turf Club medical officer Walter Halley.
Carberry initially injured his ribs in a fall while out hunting.
