Collingwood defender Jack Frost has signed a two-year contract extension, ensuring he remains a Magpie until at least the end of the 2016 AFL season.

Taken at selection No. 46 in the December 2012 Rookie Draft, Frost has emerged as a pivotal member of both the Collingwood backline and the club’s next generation of players.

Following a PCL injury in 2013, the 22-year-old had a stand-out 2014 season, nullifying some of the league’s best key forwards in high pressure situations and finishing the year as the only player on Collingwood’s list to play every game.

The full-back was ranked number one at Collingwood for spoils (141) and seventh overall in the competition in 2014. In only his fourth senior game, he held Lance Franklin to just two goals and four marks in the side’s round 2 win against Sydney at ANZ Stadium earlier this year.

Frost said he was thrilled to be continuing his career at Collingwood and thanked the club for the faith it had shown in him.

“I’m very excited that I will be playing at Collingwood for a further two years and extremely grateful for the opportunity that the club has given me.

“We have a fantastic group of players and a real belief in the direction we are going and I look forward to hopefully playing a key role in that”.

Director of Football Rodney Eade said Frost’s promising growth as an AFL footballer has the club enthusiastic about what lies ahead.

“Jack is part of the next generation of young talent whose progress has provided a window on an exciting future for the club,” Eade said.

“Since joining Collingwood in 2012, Jack has tackled every challenge thrown his way with great enthusiasm, and embraced the responsibility which comes with playing a key role at senior level.

“We’ve been delighted by Jack’s ability to stand up as a young leader and certainly look forward to his continued development in the years to come.”
