It was subsequently announced on Friday that - following Weir's arrest and release without charge after search warrants acted upon by Victoria Police at two properties - he and McLean were both issued show-cause notices over the possible suspensions of their licences and refusal of entries.
Queensland Racing Integrity Commissioner Ross Barnett said QRIC was not taking any immediate action against Weir or his Warrnambool foreman, licensed trainer Jarrod Mclean.
Darren Weir's training career hangs in the balance after Racing Victoria stewards adjourned a marathon inquiry into alleged animal cruelty and corruption.
Several Weir-trained horses are due to race in Victoria over the weekend.
On Wednesday, police seized a firearm, a substance believed to be cocaine, and four illegal Taser-type devices at the Melbourne Cup-winner's stables.
"The Show Cause Notice was issued in light of the seriousness of the reported allegations concerning Mr Weir and the responsibility of Racing NSW to protect the image, interests and integrity of racing, further noting that Mr Weir has nominated a number of horses for the Golden Slipper and nominations for The Championships are approaching", Racing NSW said.

In New Delhi , Ministry of External Affairs Spokesperson Raveesh Kumar said, "We are aware about this incident". The ministry has also established a 24/7 helpline in the Indian Embassy in Washington for assistance.
"Darren Weir over several years has broken all the records and he's become our premiership-winning trainer", Dabernig told the radio station. It called on Racing Victoria to deny Weir's nominations until the matter was fully dealt with, something that has since happened. In theory, it will then quicken immediately when the whip is used in a race, as it expects the pain of an electric shock to follow close behind.
Victoria Police says the allegations include obtaining financial advantage by deception, engaging in conduct that corrupts a betting outcome and use of corrupt conduct information for betting purposes, as well as animal cruelty.
The 48-year-old, who claimed a landmark win in the 2015 Melbourne Cup when jockey Michelle Payne won aboard Prince Of Penzance, is also charged with failing to help the inquiry and conduct prejudicial to the interests of horse racing.
A five-time Melbourne premiership victor, Weir runs the biggest stable in the country with more than 600 horses on the books and dozens of staff at both locations.
