Sydney star Adam Goodes has been given extended leave by the AFL club as he continues to come to grips with the booing controversy.

Goodes was given two days away from the club to gather himself after he was loudly booed by sections of the West Coast crowd at the weekend - a reaction he and teammate Lewis Jetta considered racist.

The veteran Swan was so upset by the furore he was said to be considering his future in the game.

"As a club, we are working with Adam and those close to him and supporting him through what is a really difficult time," club chief executive Andrew Ireland said in a statement released on Wednesday.

"Adam is sick and tired of this behaviour. It has been happening for too long and it has taken its toll.

"We will give Adam all the time he needs. We will keep supporting him and he will return to the club whenever he is ready."
