Sydney ruckman Darcy Cameron has played just one AFL game across his career, although that hasn't stopped three clubs from inquiring about his services.
The 23-year-old made his AFL debut in round 18 last year, and had a solid NEAFL campaign in 2018, finishing second in the league's MVP award.
GWS are thought to be at the head of the queue for the big man, who can also play in the forward line when resting.
Carlton and North Melbourne are set to also battle it out for Cameron's signature, with both clubs set to offer him the number one ruck position, according to AFL.com.au.
Despite Cameron coming off-contract at the end of the season, another club would need to trade for him - unless the Swans delist him.
