Trainer Robbie Hennessy is pleased an explanation has been found for that display and is also thrilled his charge does not require a breathing operation.
Rubi Light will now drop in trip for the Paddy Power Dial-A-Bet Chase at Leopardstown on December 27, rather than run in the Lexus Chase a day later.
“We put an on-board scope on him on Friday and galloped him hard,” said County Meath-based Hennessy.
“It showed up that he had mucus on his lungs and, in a way, it was a bit of a relief.
“Barry Geraghty said when he got to the third-last he stopped very quickly and his breathing didn’t sound right.
“We were fearing that he might need a breathing op so I’m delighted that we’ve found the infection as it’s easily treated.
“He’s on something now until Christmas Day and hopefully he’ll be fine to run in the Dial-A-Bet on the 27th – I think that looks the best option.
“I know it’s two miles, but the Lexus looks very hot this year.”
Days Hotel is unlikely to run in the Paddy Power Dial-A-Bet Chase at Leopardstown.
The seven-year-old showed smart form as a novice last season but had his campaign cut short through injury.
On his return from over 12 months off he beat a good field to win the Hilly Way Chase at Cork, but trainer Henry de Bromhead will resist the lure of the Grade One in favour of the Kinloch Brae Chase at Thurles on January 17.
“I think we’re going to give it (Leopardstown) a miss with him,” said De Bromhead.
“At this stage we’re working towards the Kinloch Brae Chase at Thurles.
“He’d been off for a year so I just thought it might be a bit quick for him to run again at Leopardstown.
“He jumps for fun and appreciates the really deep ground.
“I was absolutely delighted with him in the Hilly Way, having been off for so long to win as he did was a tremendous performance.”
