Essendon's Irish defender, Cono McKenna, has committed his long term future to the club, signing a four-year contract extension.

McKenna, who made his debut in 2015, playing two games, cemented his place in the Bombers' line-up this year, starring with his pace off half-back, playing 19 matches and averaging 17 disposals.

The 21-year-old said the new deal, which will see him remain at the club until 2021, was an easy decision.

“Essendon has made my transition into football an easy and enjoyable one,” McKenna said.

“We have a great group of players, and the strong bonds I’ve made with my teammates have helped me develop my game and drive me to want to achieve success.

“I’ve enjoyed every moment with the club and am happy I will continue to represent the club for another four years.

“I believe in our vision, we have an exciting future and over the next four years I hope we can achieve the success we are working towards.”

Coach John Worsfold said McKenna has become a key member of the side.

“We are very pleased Conor has re-signed with the club,” Worsfold said.

“His efforts week in, week out, has made him a fundamental part of the squad.

"Conor is still learning our game and with continued hard work he will improve rapidly and become an outstanding rebounding defender.

“Conor is an incredible fit for what we are building at Essendon.”

McKenna was recruited as a Category B Rookie from County Tyrone in Ireland in 2014.
