Ugo Foscolo's fledgling Australian career has been put on hold.

The New Zealand-owned three-year-old was turned out after his unplaced run in the Gr.1 Canterbury Stakes in his first appearance from the leading Sydney stable of Gai Waterhouse and Adrian Bott.

"He's out spelling after that one run on a very, very heavy track," racing manager Emma Pearce said.

"He pulled up quite muscle sore over his back and hind quarters so Gai decided to put him in the paddock and let him mature further.

"He'll probably have six weeks out. We all know he is so much better than we saw in that one run."

Ugo Foscolo had been a runaway trial winner at Warwick Farm before he was undone by the testing Randwick going in his Australian debut earlier this month.

The Zacinto three-year-old previously won five of his six starts, including the Gr.1 New Zealand 2000 Guineas, from Stephen Marsh's Cambridge stable.

Kevin Hickman and Todd Bawden shared in the original ownership syndicate of the gelding before they bought out their former partners and the horse was transferred to Waterhouse and Bott.

Meanwhile, the Sydney trainers are pleased with the progress of the New Zealand-bred mare Replique.

Her best Australian performance from a handful of starts was a sixth placing in the Gr.3 Angst Stakes at Randwick last spring.

The daughter of Darci Brahma won the Listed Southland Guineas last season from Nick Wigley's Rangiora stable prior to a change of ownership.

"She will trial again, probably at Randwick on Friday and if not the following week," Pearce said.

"Gai will look for a suitable race to get her back to winning ways to get her confidence back."
