Celtic have confirmed that Boudewijn Zenden will not be joining the club on a permanent basis.
A statement on the club's official website said Celtic were "delighted" that the Dutchman had trained with the Scottish Premier League side.
"But both parties have agreed not to take the move further following discussions," the statement continued.
"Everyone at Celtic would like to wish the player their sincere best wishes in his future career."
Former Barcelona, Chelsea and Liverpool midfielder Zenden, who won 54 caps for the Netherlands, was most recently with Sunderland.
The 35-year-old left the Black Cats at the end of last season and is currently without a club.
