ACT apprentice Kayla Nisbet has had many hard-luck stories.

Just days after returning to riding after suffering a fractured foot, Canberra apprentice Kayla Nisbet has been sidelined again - with a broken wrist.

The 19-year-old was injuredduring trackwork at trainer David Hayes' Lindsay Park property in Euroa, in Victoria, on Monday and is likely to be sidelined for a couple of months.

''It is in a cast at the moment and she's going to have a wire put in it tomorrow in an operation,'' her manager Ryan Roberts said.

''The cast has got to be on for six weeks and then obviously they reassess once the cast comes off.''

Nisbet spent a month out due to the fractured foot and made a winning return at Moonee Valley on Friday night.

She missed a golden opportunity on short-priced favourite Lord Of The Sky at Caulfield on Saturday when she was caught in traffic. Nisbet arrived at Caulfield as the horse was going on to the track and had to watch from the sidelines as Jake Duffy guided the Robbie Laing-trained sprinter to victory.

''That's hopefully the three bad luck stories out of the way. They say things happen in threes, so hopefully that's it done now,'' Roberts said.

Roberts said Nisbet was trotting up on a two-year-old getting ready to work and the horse ducked away from something, causing the saddle to slip.

''She fell off and landed on her wrist,'' Roberts said.
