Noel Callow is free to resume his riding career after being cleared by Malaysian stewards who stood him down due to an irregularity in a drug test.

Callow will resume riding at the Bletchingly Stakes meeting at Caulfield on Saturday week.

A urine sample taken from Callow in Malaysia last month showed an irregularity to two banned substances.

Subsequent tests on Callow's B sample by an independent laboratory were clear and he was told by Malaysian stewards on Monday he could resume riding.

They stood Callow down from rides in Kuala Lumpur on June 13 after traces of the prohibited substances ephedrine and phentermine were found.

The leading jockey was two meetings into a comeback after a six month break and had ridden four winners from seven rides.

Reece Murphy, who manages Callow, said he would be able to ride at around 55.5kg to 56kg when he resumes at the first metropolitan meeting of the new season.

The effervescent jockey was dubbed "King Callow" by his army of followers when he was leading rider in Singapore for two seasons.

He became the first jockey to reach the 100-winner milestone in Singapore, riding a record 106 winners in his first season there in 2007.

Callow quit Singapore in January because he was struggling with his weight and he returned to Victoria where he tried his hand at media commentary.

Before leaving Australia, Callow had ridden three Group One winners - In Top Swing in the 2003 Caulfield Guineas, Al Maher in the 2004 Australian Guineas and Benicio in the 2005 Victoria Derby.
