Sirileo Miss is set to return to racing at Bendigo on Saturday after a 12-month absence.
Racing Victoria stewards had banned her, along with four others, for testing positive for prohibited substances Formestane and 4-Hydroxylestesterone.
While stewards continue to investigate the positives, three of the five horses, including Sirileo Miss, are now allowed to compete in jumpouts, trials, and races.
Trainer Symon Wilde expressed relief at the lifting of the ban, acknowledging the frustration of missing out on her prime.
Despite the long layoff, he remains cautiously optimistic about her comeback.
The other two horses reinstated are Circle Of Magic and Lake Tai, while Alphaville has been retired, and Yulara’s ban extends until April 13.
