THE AFL Players' Association will investigate the conduct of Adam Treloar's manager regarding the circumstances that led to the former Giant’s hip operation.
Greater Western Sydney has written to the association, which is responsible for the conduct of player agents, asking it to examine the role played by Peter Blucher in arranging the secret operation.
"The players' association has received a formal request from GWS to investigate the conduct of Adam Treloar's agent in relation to a hip operation that was organised for Adam following advice that he received from an independent medical expert and Collingwood medicos," agent accreditation board chairman Ian Prendergast told News Corp.
"We will now look into the matter further, as we do with all matters involving allegations regarding the professional standards of agents."
Treloar was traded to Collingwood on Wednesday.
Collingwood gave up its first-round picks this year (No.7 overall) and next year's first pick for Treloar, while it also gave No.65 to the Giants.
In addition to Treloar, the Giants also passed their second-round draft pick this year (No.28 overall) back to the Pies.
Treloar, 22, joined the Magpies on a long-term deal believed to be worth about $750,000 a season, having been hotly pursued by Richmond and North Melbourne before settling on Collingwood as his new home.
The Victorian played 79 games in his four seasons at GWS. He finished runner-up in the Giants' best and fairest award last season after averaging 27.5 disposals a game (ranked first at the club).
This followed his top-five finishes in the 2013 (fifth) and 2014 (fourth) award counts, and a top-10 finish in the Giants' inaugural 2012 season (ninth).
