COLLINGWOOD has extended young defender Tom Langdon's contract until the end of 2018 as the club continues to secure its talent under coach Nathan Buckley.

The announcement of the defender's signature comes on the back of Monday's news that the Pies had also tied up exciting young forward Jamie Elliott for three seasons.

Langdon took his opportunity after injury decimated the Magpies' backline early in 2014 and played 19 games in an excellent debut season.

He has been outstanding in the first five games of 2015 and appears a bargain for the Magpies after being taken with pick No.65 in the 2013 NAB AFL Draft.

Langdon now wears the number of revered Collingwood defender James Clement and looks to be following in his footsteps as a reliable mid-sized backman.

He told last month Clement had caught up with him at the season's launch.

"He was one of the best," Langdon said. 

"He just gave me some advice about how I should go about it."

Langdon told the Herald Sun he was rapt to sign for another three seasons.

"Bucks would get a lot of satisfaction from all the young guys wanting to stay and it's a really stable place at the moment," he said.

Langdon won Collingwood's best first year player in 2014 and turns 21 in June.
