ADELAIDE chief executive Stephen Trigg has pulled out of a major address at a South Australian event, as pressure mounts on the Crows over the Kurt Tippett saga.
 
Trigg had been due to speak in front of more than 200 delegates who are attending the state's Local Government Association Conference.

Swans still may get Tippett
 
A representative from the LGA confirmed to AFL.com.au Trigg was no longer delivering the key-note address at the conference, but no reason had been given.

Trigg was replaced at the function by David Grenvold, the Crows' general manager of corporate sales and service.

A day earlier, Adelaide chairman Rob Chapman declined to guarantee Trigg's future at the club as the chief executive.

"We will reach the right conclusions after this," he said on Adelaide radio station 5AA.

"Steven Trigg has been a veteran of this world, as has (former football operations manager) Johnny Reid, (current football operations manager) Phil Harper, everyone at our club.

"And they have got a history of complying with the rules and ... I don't want to speculate beyond that because that might prejudice the outcome of the investigation."

The AFL is investigating the Crows after it was revealed a secret clause was included in Tippett's 2009 contract, but not the contract that was rubber-stamped by the AFL.

There are also suggestions there was not only an arrangement to trade Tippett to the club of his choice at the end of his contract, but of an additional financial arrangement, neither of which were disclosed to the AFL as part of his contract.

It is reported that the League is looking into correspondence in 2009 between the Crows and Velocity Sports, the company that manages Kurt Tippett.

Adelaide's The Advertiser raised the prospect that the third-party breach might relate to the Crows paying Joel Tippett, Kurt's brother, to move from the Gold Coast to Adelaide in 2012 to help ease Kurt's homesickness.

Joel played two games for Gold Coast in 2011 and joined SANFL club West Adelaide this year.

The League announced on Wednesday it was investigating the matter and the Crows are facing the prospect of heavy sanctions for both the trade clause and the third-party financial agreement.
