Queensland racing authorities have suspended the licenses of two thoroughbred horse racing participants.
It comes after a photo was widely circulated allegedly depicting a jockey holding an object in his hand that looks similar to a jigger at Birdsville race track on Tuesday.
Training has been underway in the lead-up to the iconic Birdsville Races, which are expected to attract more than 6,000 spectators and jockeys to the tiny outback town.
