Fremantle chief executive Steve Rosich says the money spent on Nat Fyfe’s new three-year deal will not exclude the Dockers from nabbing a player under free agency at the end of the season.

The Dockers announced on Thursday that Fyfe would stay with the club until the end of the 2017 season, ending six months of speculation on his future.

Fyfe, 22, is believed to have become the Dockers' highest-paid player, with the deal rumoured to be worth about $2.5 million, but it’s his next contract that should really set his bank balance ablaze.

When he is next out of contract, he will qualify as a restricted free agent, which means the Dockers would need to match offers from rival clubs to keep him.
