Navan is rescheduled for next Tuesday

Racing News round-up: Tomorrow's Navan fixture has been cancelled - with the meeting instead transferred to next Tuesday.

Explaining the switch, a spokesperson for Horse Racing Ireland said yesterday: "Wednesday's meeting was cancelled for health and safety reasons. It's to do with the new weighing room and building work that has been going on over the summer, which is just not quite finished at the moment."

The original programme of races will be staged but fresh entries for the meeting must be made by 12 noon on Thursday.

Entries that have already been made must still be repeated, however, and declarations to run must then be confirmed by 10am on Monday, October 16th. Although the transferred meeting is subject to an 8am inspection on October 16th, no further setbacks are envisaged.

Macs Joy, meanwhile, is likely to tread a similar path to last season as he shapes towards launching another assault on the jumping calendar's major hurdling prizes.

Jessica Harrington's classy seven-year-old chased home Brave Inca in the Champion Hurdle last March before gaining revenge on Colm Murphy's star in the Grade One ACC Bank Champion Hurdle at the Punchestown Festival.

While Harrington has not ruled out sending the gelding over fences in the future, she is keen to keep him over timber this season. "If he hadn't won in Punchestown I suppose we would have thought about chasing but thankfully, he managed to win and he's still a year younger than Brave Inca so we could always go chasing next year," said the Co Kildare handler.

Jim Bolger's unbeaten colt Teofilo heads a high-class list of 25 juveniles engaged at the five-day confirmation stage for Saturday's Darley Dewhurst Stakes Last month's National Stakes hero could again lock horns with his vanquished Curragh rival Holy Roman Emperor, who spearheads a nine-strong Aidan O'Brien entry for the Newmarket contest.

The Danehill colt subsequently ran out an impressive winner of the Grand Criterium at Longchamp and could be joined by Eagle Mountain, an emphatic seven-length winner of Sunday's Beresford Stakes.

Sir Percy is 4 to 1 favourite to add the Emirates Airline Champion Stakes on the same card to his Vodafone Derby triumph. Ladbrokes installed the Marcus Tregoning-trained colt as market leader after 15 horses were confirmed for the Group One showpiece over a mile and a quarter, including the 2005 Prix de l'Arc de Triomphe hero Hurricane Run and multiple Group One-winning mare Ouija Board.
