West Coast Eagles Mackenzie was drafted in the 2nd round of the 2006 AFL Draft. A key position defender, he had his best season to date in 2014. He replaced the retiring
Darren Glass as the club's leading backman and was named acting co-captain of the club for the remainder of the season, along with four other players. He ended the year by winning the Eagles'
best and fairest award, the
John Worsfold Medal, beating
Brownlow Medallist
Matt Priddis by 11 votes. He missed the entire
2015 AFL season after tearing his
anterior cruciate ligament in West Coast's first pre-season game of the year against Carlton. In the final minutes of the 2017 Elimination Final played against
Port Adelaide Power, with scores level, Mackenzie kept Port Adelaide from scoring a behind, throwing the full force of his body into the point post in the process. This helped force the Elimination Final into extra time, where the Eagles emerged victorious. Mackenzie retired at the end of the 2018 season, after consistent troubles with injury. == References ==
