Former Swan and Crow, Tony Armstrong, became a Magpie when he joined Collingwood as a delisted free agent on Thursday morning.

Armstrong’s imminent arrival at the Westpac Centre completes the club’s pre-draft trading, with the final touches to the list for 2014 to be made through the AFL national draft on November 21. General Manager of List Management Derek Hine will take two first round selections, 6 and 10, to the Gold Coast in a fortnight.

Armstrong comes to Collingwood after four seasons with Adelaide and two more with Sydney, in which time he played 29 matches as a small defender. He was recruited from the Calder Cannons by the Crows with pick 58 in the 2007 national draft. Most recently, the 24 year-old represented Australia in the two test international rules series against the Irish in Ireland.

He remains overseas and will commence training with the Magpies on November 18.

“Tony is a lovely kick, with either foot, and a pacey defender we think can make a strong contribution,” Hine said.

“He has played senior football and what he is capable of was on display in the NEAFL grand final when he won the Alex Jesaulenko medal as best afield.”

Apart from piquing the curiosity of football’s ornithologists, Armstrong becomes the fourth mature recruit Collingwood has added to its list in the off-season, with his one-time Sydney team-mate Jesse White, Patrick Karnezis and Taylor Adams secured in the initial free agency/trade period.
