Bradford boss Peter Taylor confirmed that Zesh Rehman has joined Thai champions Muang Thong United.
"This move is a good opportunity for him because we couldn't guarantee him a starting place," Taylor told the club's website.
"We wish him all the best at Muang Thong, he is welcome back any time."
He was expected to leave following Taylor's decision to strip him of his captaincy for criticising his team selection on a live radio show.
Rehman, English-born but a Pakistan international, became the first South Asian to play in the English top flight when he made his debut for Fulham, for whom he made 30 appearances.
Muang Thong United is Thailand's richest club, owned mostly by a local media company and boasting a new stadium with a capacity of 25,000.
They won the Thailand Premier League title in 2009 in their first season in the top flight.
