TRAMORE PREVIEW:THE WELL-TOUTED, if unraced, colt Zulu Chief is to lead a select group of Aidan O'Brien-trained horses into this week's Craven meeting at Newmarket.

Zulu Chief, a half-brother to Hawk Wing, is listed in some ante-post markets as a possible 2,000 contender next month, despite not having run before.

"We think he is a nice horse and he is ready to go to a maiden on Thursday," O'Brien said yesterday.

"Poet is in a Listed race on Wednesday (Fielden Stakes), and The Bogberry could run in the Craven on Thursday. Psalm is not a definite to run in the Nell Gwyn."

In the continued absence of the injured Davy Russell, Ruby Walsh will attempt to maintain his championship momentum at Tramore today where Swiftmarc can score for the champion jockey in the second handicap hurdle.

Nell's Oscar has Rare Article to beat in the bumper, but should be able to cope better than when beaten by Sallie's Secret at Cork.
