Trainer Clarry Conners says Assail is still a chance of jumping in the $3.5 million Golden Slipper at Rosehill in April, but the daughter of Redoute's Choice is no chance of running in next month's Black Opal Stakes.
Instead, Conners is hoping to run her in a trial at Rosehill on March 5 before targeting a fillies' race in Sydney.
Assail has won both her starts - the Wyong Magic Millions two-year-old classic and a two-year-old handicap at Warwick Farm - for $210,750 in total prizemoney.
The Redoute's Choice filly is part-owned by Canberra duo Kevin Matthews and Igor Brkic, who went to the Gold Coast for her Magic Millions' campaign, aborted because she has a foot abscess.
She has been recovering in the paddock after having a big chunk of the outside of her hoof removed.
Since the operation Assail has been in a race against time for her hoof to heal sufficiently to run in the Slipper, the world's richest race for two-year-olds. She has slipped to the fifth line of betting at $26, ACTTAB says.
Conners said Assail was already back in work. ''She hasn't done any fast work yet, but she's there working and swimming so we've just got to bide our time and decide when I think she's ready to gallop,'' he told The Canberra Times.
''[The Golden Slipper] is still there, we're still trying for it.''
Brkic is also a part-owner of Without A Shadow, trained by Canberra's Nick Olive, which will jump in the Lightning Ridge Plate (1000 metres) at Thoroughbred Park on Sunday. Whoever wins the Lightning Ridge automatically qualifies for the listed $250,000 Black Opal (1200m) at Canberra in a fortnight.
