Geelong defender Lachie Henderson has announced his retirement from the game, while Irish Cat Stefan Okunbor will return to his home nation.

Henderson hangs up the boots after 206 career games, ranging across stints with the Cats, Lions and Blues, first making his AFL debut in 2008.

The 31-year-old made his debut with Brisbane after being selected via the 2007 National Draft as the eighth overall pick, playing 15 games for the Queensland club before moving to Princes Park ahead of the 2010 season.

Henderson would play 102 games for the Blues between 2010-2015 before venturing to Kardinia Park.

Okunbor was recruited to the Cats as a Category B Rookie from Ireland, and will return back home after three years in the navy and white hoops.

Geelongโ€™s general manager of football Simon Lloyd thanks both Henderson and Okunbor for their services to the club.

โ€œLachie has made a significant contribution since joining the club in 2016,โ€ Lloyd said.

โ€œHe was aย strongย clubman andย always focused on improving his teammates.ย Lachie could always be depended on andย helped the club to the finals in each of his seasons with us.

โ€œStefan showed great desire and commitment to become a better player. He was limited by injury and the lack of games through the shutdown. He is now back in Ireland and we hope he can enjoy a successful Gaelic football career.

โ€œEveryone at the club wishes Lachie and Stefan well in their future endeavours.โ€
