Tippett's manager, Peter Blucher, has called upon the Crows to hold their end in a 'gentleman's agreement' to help the 25-year-old get to the club of his choice.
Blucher denied reports that a clause in Tippett's contract stipulated he could go to a club for his choice for just a second-round pick.

A report in The Age says the Swans have told veteran midfielder Jude Bolton there is a place on their list for him in 2013 should he want to play on.
Bolton turns 33 in March.
The Age also reports Collingwood and Melbourne have had talks on moving Sharrod Wellingham and Chris Dawes to the Demons for the fourth overall pick.
Wellingham had nominated West Coast as his club of choice and his manager insists he has no interest in moving to the Demons.
For its part, Melbourne may yet be forced to use the third overall pick on father-son choice Jack Viney, meaning it may not be so keen to trade away the fourth pick.
AFL.com.au understands Port Adelaide has joined the party, tabling a deal for Wellingham.
