Banned ex-Adelaide forward Kurt Tippett's manager is under investigation by the AFL players' association (AFLPA).
Tippett, Adelaide and past and present Crows officials were last week sanctioned for breaching draft and salary cap rules, but the AFL is unable to penalise managers.
However, the AFLPA said on Tuesday they had launched their own probe into Tippett's manager Peter Blucher, who helped engineer the deals that have resulted in the player having to sit out the first 11 games of next season.
"Following the AFL Commission hearing into breaches and conduct prejudicial to the draft and total player payments (TPP) provisions of the AFL rules, the AFL Players' Association has now commenced an investigation into the role of Kurt Tippett's accredited agent, Peter Blucher," the AFLPA said in a statement.
The agent accreditation board governs the investigation.
An investigator will be appointed to establish the facts and report their findings to the board, along with any recommended sanctions.
The process could potentially result in Blucher being deregistered as an agent.
Tippett is considered likely to make his way to his preferred club Sydney in next Tuesday's pre-season draft although Greater Western Sydney, who have the No.1 pick, could spoil those plans.
