Collingwood young guns Brayden Sier and Will Kelly have each signed a two-year contract extension with the club.

Sier’s deal will see him tied to the club until 2021, the 21-year-old playing 18 matches since he was selected with pick 32 in the 2015 national draft.

Sier’s 2018 debut was long awaited due to injury setbacks, however the tough inside-midfielder has gradually found consistency over the past two seasons.

Alongside Sier, 2018 father-son selection Kelly has extended his tenure at the club until the end of 2022.

Kelly arrived at Collingwood after an impressive performance in the Oakleigh Chargers’ 2018 grand final campaign despite suffering an ankle injury.

As a result, the 19-year-old defender had a delayed start to the year and managed four VFL games before sustaining a hamstring injury.

Collingwood List Manager Ned Guy said the pair were full of promise.

“We’ve seen some really positive signs from Brayden over the past couple of years and as he continues to grow and develop, he can play an important role in our midfield going forward,” Guy said.

“Will has joined the club and applied himself with upmost dedication and focus as he works on getting his body right to get back on the field, hopefully it won’t be long until our supporters can see what he’s capable of.

“Brayden and Will have plenty of potential and we look forward to watching them grow in the black and white stripes over the next few years.”
