Mason Cox

Cox was seeking permanent resident status on a path towards Australian citizenship to fulfill his desire to live the rest of his life in Australia, committing to a multi-year contract at Collingwood. At the end of March 2020, he was accepted to become an Australian citizen.

In the 2018 Preliminary Final against Richmond Football Club he played a man of the match performance kicking three goals consecutively and taking many contested marks, Bruce McAvaney remarked "what has Collingwood unleashed" when talking about Mason's performance.

In the 2018 Grand Final he kicked 2 goals during the 3rd quarter and took many contested marks, while playing in Collingwood's loss.

On September 11, 2017, despite interest from other clubs, Cox signed a three-year contract extension, keeping him at Collingwood until the end of 2020. Cox continued his good form in the 2018 season, kicking a career-high 5 goals in the Queen's Birthday match at the MCG and was awarded the Neale Daniher trophy as Best on Ground.

After playing well in the opening two games of the 2016 VFL season, he made his AFL debut on April 25, 2016 in the annual Anzac Day match against Essendon. Within the first 80 seconds of the match, he took his first mark and scored the game's first goal with his first kick in the AFL. Collingwood went on to win the match by 69 points.

Cox played for the Collingwood reserves team in the Victorian Football League (VFL) throughout the 2015 season whilst learning the game and improving his skills.

Cox studied engineering at Oklahoma State University, graduating in 2014. While studying, he started playing basketball as a hobby. He initially joined the Oklahoma State Cowgirls' "scout team" to simulate Brittney Griner, former Baylor University basketball player. After being noticed by former head coach, Travis Ford, he was asked to join the university's men's basketball team as a walk-on. He played a total of 57 minutes for the Cowboys, scoring seven points. One of his highlights while playing NCAA Division I basketball was shutting down future National Basketball Association star Joel Embiid while defending him.

Cox was invited to attend the 2014 US International Combine for potential Australian rules footballers, in Los Angeles in April 2014. After impressive performances in the skills testing he traveled to Australia for a second combine and on May 30, 2014, was signed by the Collingwood Football Club. AFL teams Port Adelaide, North Melbourne, Richmond, and Fremantle were also reported as having shown interest in recruiting Cox.
