The Suns have confirmed Martin has handed in a trade request.
“Jack Martin has informed the club that he will request a trade during the exchange period next month,” GOld Coast’s General Manager of Football Operations Jon Haines told the club’s website.
“Jack and his manager will work through his options, as will the club’s list management team, in a bid to get the best possible outcome.”
Drafted as pick one in the 2012 ‘Mini Draft’, Martin has endured a tough first six years with the Suns, amassing 97 games while being frequently hampered by injury.
However, the Claremont product has finished in the Suns’ top three in the best and fairest count on two occasions and is expected to request a salary of upwards of $600,000.
The Blues are the front-runners to secure hard-nut Papley, who is said to be wanting a return home to Victoria for family reasons after four seasons with Sydney.
The 23-year-old enjoyed a career-best season in 2019, kicking 37 goals including a five-goal performance against reigning premiers West Coast in round 12.
Adelaide’s 11th-placed finish means that Carlton will receive pick eight in this year’s draft after their pick swap last year.
The Blues might be able to use that selection to trade for two later first-round picks that would help them secure Papley and Martin if he requests a trade for Carlton.
The Suns will pitch for a priority pick at Tuesday’s AFL commission meeting after another poor season – with Martin’s departure bolstering their claims.
