CHORLTON-BORN jockey Darryll Holland has had to reshuffle his riding plans for tomorrow.

He was all set to go to Chester but has picked up the plum ride on Aidan O'Brien's main challenger Tycoon in the St Leger at Doncaster.

Holland has had three rides in the race, finishing unplaced on Kuwait Trooper in 2000, second on Highest in 2002 and third behind O'Brien's winner Brian Boru 12 months ago.

His agent Matt Chapman said: "Darryll is thrilled to have got the ride.

"The call for Tycoon came out the blue, although Aidan knew Darryll was keen to ride the horse."

Tycoon is currently fifth in the betting for the race after a poor run in the Juddmonte International at York.

Before that, he was an unlucky sixth in the King George VI and Queen Elizabeth Diamond Stakes at Ascot when he was hampered as pacemaker Lunar Sovereign came to the end of his tether.

That run proved his third place at 150-1 in the Irish Derby behind Grey Swallow and North Light was no fluke and a repeat of that running would give him a great chance as tomorrow's hot favourite Rule Of Law was a neck behind in fourth with Let The Lion Roar another two and a half lengths back in fifth.

But, while Tycoon flopped so lamentably at York where he trailed in a distant last, Rule Of Law strengthened his claims on the same card when beating Let The Lion Roar in the Great Voltigeur.

The Lion could get a lot closer this time as he is bred to appreciate the extra distance of tomorrow's race while Tycoon also has plenty of stamina.

Sir Michael Stoute, bidding for his first win in the world's oldest classic, finally decided to let his Yorkshire Oaks winner Quiff take her chance despite doubts over the drying ground all week. His other contender Maraahel cannot be ruled out either, as he is steadily improving.

Percussionist also enters calculations but Franc Sonata is best on softer ground while Czech raider Darsalam has only faced poor rivals at home.
