Midfielder David Fox has returned to Colchester United, after signing a three month deal with the U's.
"He fits our profile of how we want to play the game and will be a good addition to the squad for the coming months."
"David adds experience to a young squad," boss Tony Humes told the official website.
He was released by the Canaries at the end of his contract this summer and has been training at Preston North End prior to coming to do the same at the U's.
