Sydney Swans great Josh Kennedy has confirmed this season will be his last, announcing he'll be hanging up the boots at the end of 2022.

The 2012 premiership player, a three-time All-Australian and three-time winner of the Bob Skilton Medal for Sydney's best and fairest, Kennedy has struggled with injury this year.

He suffered a left hamstring injury in the Swans' VFL match against North Melbourne on Sunday, having injured his right hamstring against Carlton in May, which resulted in eight weeks out of the game.

"It was on the other side, it's not the hamstring he did early in the season," coach John Longmire said after the match.

"He told me, 'I just pulled up a bit short at the start of the second quarter and knew I'd done something and would stop the game'."

The midfielder joined the Swans from Hawthorn for the 2010 season, captaining the side from 2017-2021.
