Baird made 165 apperances for Fulham before leaving the club in 2013 and is looking forward to the return to Craven Cottage.
“When the opportunity arose I had no doubt in my mind that I wanted to come and be part of this again,” he told the club’s official website.
“I’m looking forward to playing in front of the fans again. They were fantastic to me over the six years that I was here previously.”
