The Adelaide Crows and its chief executive Steven Trigg have been slapped with more charges as they prepare to face the AFL commission on Monday.

The extra charges relate to alleged payments made to Tippett that were outside of the salary cap.

The news comes as star forward Kurt Tippett declared his innocence and threatened to sue the Crows if the AFL decided to de-register him, News Limited reported.

AFL general manager Adrian Anderson revealed the details of the new charges in a press release today.

"In accordance with AFL Player Rule 17, which relates to the enforcement of the AFL Draft and Total Player Payments, I have today issued a further three charges. The Adelaide Crows Football Club, Adelaide Crows Chief Executive Officer Steven Trigg and Adelaide Crows General Manager Football Operations Phil Harper have each been charged once as follows:

Contrary to Rule 17 of the Rules, between September 2009 and October 2012, you engaged in conduct in breach of the Total Player Payments provisions in the Rules.

"Again, in accordance with Rule 17, the Adelaide Crows FC, Mr Trigg and Mr Harper were each advised today in writing of the charges.

“These further charges will also be heard before the full AFL Commission next Monday, November 19, at 1pm at AFL House," Mr Anderson said.

Meanwhile, the Sydney Swans have confirmed they are still interested in signing Tippett despite the ongoing investigations.

"We are still keen for Kurt to become a Swans player," Swans chief executive Andrew told News Limited.

The good news for Sydney is that Tippett reportedly spurned interest from Greater Western Sydney, who have picks before the Swans in both the national and preseason drafts.
