Racing NSW stewards will hold an inquiry into a positive sample returned by apprentice Deanne Panya after another regarding a fall in which she was injured.

Injured apprentice jockey Deanne Panya has more on her mind than a broken collarbone with stewards calling her to an inquiry over a positive swab to a banned substance.

Before she answers questions regarding the positive test from a January 2 sample, Panya will attend an inquiry on Thursday into the fall on January 28 in which she suffered the collarbone injury and facial lacerations.

Panya came off Sebring Express in the straight during the Widden Stakes.

Her positive result is believed to be to a diuretic, banned under the rules of racing.
