Former Kiwi rider Ryan Bishop is still up to a month away from returning to the saddle after fracturing his ribs in a fall during the Magic Millions 2YO on February 24.

And, Singapore apprentice Simon Kok has gone home after fracturing his ankle when his mount reared in the barriers prior to the first race on Launceston Cup day.

However, in better news, three-time premier jockey David Pires is finally making progress in his recovery from a career-threatening broken hip.

He was injured in a five-horse fall at Elwick in February last year and medical advice was that he would be sidelined for at least 12 months.

While attending a race meeting at Mowbray over the carnival, Pires said he was not recovering as quickly as he would have hoped.

However, Tasmanian Jockeys Association general manager Kevin Ring said on Monday that Pires had since received an improved prognosis.

"I believe he has turned the corner and could be back riding trackwork within a month, depending on how things go," Ring said.

Simon Kok arrived in Tasmania in mid-December to spend three months with the Leon Wells training operation and created a good impression while riding four winners in the state.

"It will obviously take him a while to recover from a fractured ankle and, as he was coming towards the end of his time, he went home early," Ring said.

"He's gone back to (trainer) Steven Burridge."

Trainer Adam Trinder is confident Mystic Journey won't let him down in the $5 million All-Star Mile at Flemington on Saturday.

"I'm sure she'll run really well - she's never let me down before," Trinder said.

"She bounced back in really good order (after her Australian Guineas win) and has pulled up well.

"I gave her a little bit of fast work on Saturday morning and she was nice and bright."

Although Mystic Journey normally has at least three weeks between runs, Trinder does not think a two-week break will be an issue.

"She travels really well, relaxes, and eats and drinks normally - the trip over is pretty much like spending a night in her stable except she's moving 380km."
