As Boban prepares to resurrect his career following a bleeding ban, trainer Chris Waller has cautioned against expectations the horse can repeat his heroics of last spring.

Boban will be one of three Waller-trained runners in Saturday's Missile Stakes at Randwick, the first Group race of the new Sydney season.

First-up since the Queen Elizabeth Stakes in April when he bled, Boban was one of the banner horses of last year's spring carnival when he was undefeated in five starts and notched a brace of Group One victories.

But the bleeding attack has forced a different approach to the five-year-old's training and Boban will be restricted to 1600-metre races this preparation.

Waller says past experience with the issue has taught him not to put the horse under undue pressure.

"It's told me not to try him over 2000 metres, it puts a bit of extra pressure on him," Waller said.

"I'll keep him to the shorter trips, including a mile. We'll just gradually get him fit and up to that (top) level."

Hawkspur and Weary will also represent Waller in the Missile.

The former is being set for the Turnbull Stakes in Melbourne while the Epsom Handicap is the mission for Weary.

At his first Australian campaign, Weary was Group One-placed in the Doncaster Mile and All Aged Stakes.

He usually performs fresh but Waller is concerned about a firm track on Saturday.

"He did a great job in the autumn and he's come back well," Waller said.

"I'm just not sure on a good track how well he will sprint. A lot of that form in the autumn was on dead to slow tracks."

Meanwhile, Peter Snowden is yet to decide if Inkling will take his place in The Rosebud citing concerns over the horse's 59kg topweight and wide draw.

"I'm a bit 50-50. If he wins here you're a genius, if he doesn't you're kicking yourself," Snowden said.

If Inkling does not run he is likely to head to the San Domenico Stakes a week later.
