The fee for the Republic of Ireland winger has not been disclosed, but it has been confirmed Duff, 30, has signed for three years.

Duff joined Newcastle from Chelsea during the summer of 2006, and went on to play 86 times, scoring six goals, the last of which came in the opening match of the Championship season at West Bromwich Albion.

"I am happy that my move to Fulham has been completed," said Duff, who made his breakthrough at Blackburn Rovers, on Fulham's official club website.

"Fulham had a fantastic season last year and I know having spoken to the manager that the club's ambitions remain high and I am looking forward to the challenges ahead."

Fulham manager Roy Hodgson added: "I am delighted to add a player of Damien Duff's calibre to our squad, and welcome the further midfield options he provides us with. I have known Damien for over a decade since he broke into the first team at Blackburn when I was manager, so I'm fully aware of his qualities and I am looking forward to working with him again."
