FIFA have granted Celtic special dispensation to sign striker John Guidetti on loan from Manchester City.
The Scottish champions failed to complete the necessary paperwork before Monday's transfer deadline, but an appeal to FIFA was submitted on their behalf by the country's football authorities.
That appeal has succeeded, and the 22-year-old Swede is free to move north on a season-long loan as planned.
A FIFA spokesperson said: "After checking the documentation received and the information contained in the international transfer matching system managed by FIFA TMS, the Scottish Football Association was informed today that the envisaged loan deal may proceed."
Guidetti found first-team opportunities limited at the Etihad after moving from Sweden as a 16-year-old and has spent several spells out on loan with Burnley, Stoke and most notably Feyenoord where he scored 20 goals in 23 games.
The Swede is excited by the prospect of life in Glasgow and said: “I feel in great shape as it’s been great to get a long pre-season with City. But I miss getting to play games, it’s what I live for."
