The 20-year-old is the third Collingwood player in four years to produce a positive test. Josh Thomas and Lachie Keeffe,who now plays at GWS,accepted backdated two-year suspensions in 2015.
In 2012,then Collingwood CEO Gary Pert warned the league about player behaviour during the off-season that he described as “volcanic”,with regards to illicit drug taking.
The Magpies are preparing for their first finals series in five years,but Murray will be unavailable for selection as he is believed to be under a provisional suspension as the Australian Sports Anti-Doping Authority awaits confirmation of the B sample in what is a lengthy process.
In an at-times testy interview with Gerard Whateley on SEN on Thursday morning,Buckley expressed his disappointment at the situation.
“Not that I know of,” Buckley said when asked if Collingwood has an issue with illicit drugs.
“I’m really disappointed that I need to answer these questions ... this is not something that is big on our agenda right now because it’s isolated so that’s where it stays and we move on with what we can control.
“As our football has done our talking this year,our record in retrospect will do the talking so I’ll be happy to stand on that.
