The Crows and Melbourne are understood to have agreed to a trade where the Crows would gain pick 20 for Vince, who is holidaying in the US and yet to sign off on the deal.
Adelaide was likely to look at on-trading pick 20 to the Brisbane Lions for uncontracted midfielder Jared Polec, who has nominated the Power as his club of choice.
The Lions will still attempt to deal with the Crows if they can offer more for the South Australian, who has played 16 games in his three years as a Lion. However it is believed Port Adelaide is looking at a trade which would see it lose its No.13 pick but gain two reasonably high selections in return, one of which could be used for Polec.
