Collingwood has moved quickly to sign four out of contract players for next year and beyond.

Fox Sports' Jake Niall reported on AFL Tonight on Tuesday night that offers had been made to Tom Phillips, Tyson Goldsack, Travis Varcoe and Mason Cox.

Goldsack and Varcoe have both been offered one-year deals, with the veterans still proving to be important members of Collingwood's best 22.

Rising Star nominee Phillips looks set to put pen to paper on a two-year extension with the club. The 21-year-old has starred across half-forward for the Pies in 2017, averaging 20.7 touches and 4.6 marks in 16 games while ranking second for total goals assists among rising stars.

The most interesting deal of the quartet is the one that has been tabled to Mason Cox.

The 26-year-old, who has been offered a two-year deal to remain at the club, has played just seven senior games in 2017 following the emergence of Brodie Grundy as one of the premier ruckman in the competition.

Niall reported that other clubs had been "sniffing around" the big man from Texas, and despite looking like remaining at Collingwood, Niall added that Cox has "a big decision" to make in the near future.

One big uncertainty remains at Collingwood and that is the future of coach Nathan Buckley.

While offers that have already been tabled won't get pulled should Buckley not continue as coach, that may come into the decision-making process of players as they look to lock in their future.
