Midfielder David Fox, defender Elliott Ward and striker Simeon Jackson have all been retained by Norwich City after the club exercised options to extend their existing contracts.

In addition, full-back Adam Drury, who had his testimonial match against Celtic last week, has been made a contract offer which he is considering.
