SYDNEY - One of Australia's most high-profile indigenous sportsmen Adam Goodes, who was subject to repeated booing this season, has retired from Australian rules football after an illustrious career. Goodes quit in a low-key farewell to his team-mates after the Sydney Swans lost in the semi-finals of the domestic league (AFL) to North Melbourne Football Club on Saturday, calling an end to 18 seasons at the top level of the sport. "No matter how many great players we've had retire, and we've had a few over the past few years, none as great as 'Goodesy' with no disrespect to the others," Swans' coach John Longmire said after the match. "He's been an absolute icon of this footy club, and a superstar of the game." He played 372 games for the Swans and made his AFL debut for the club in 1999.
