Michelle Payne's family will leave a decision on retirement to the jockey who is recovering from abdominal surgery in a Melbourne hospital after a horrific race fall.
Doctors at Alfred Hospital are concerned about her recovery.
But her brother, Patrick, admits it might be hard to convince the Melbourne Cup winner to give away her career.
"We tried to talk her out of it a while ago," Payne told Sky Sports Radio. "We've encouraged her to retire but it's her decision. She is a pig-headed little bugger."
Payne's recovery from a split pancreas will take months and doctors are worried they may have to operate again if it does not knit together.
