Foley, who was brought to the club by former Colchester team mate Mike Walker in 1996, worked alongside Worthington and Doug Livermore with the senior side. He had previously been involved with reserve and youth sides at Colney.
Worthington was fulsome in his praise of his former colleague.
“I would like to place on record the sincere gratitude of myself and everybody at Carrow Road and Colney for all of Steve's hard work and enthusiasm over the years," said the Canaries boss, "and wish him all the very best for the future.”
“I have had 10 really enjoyable years at Norwich City, picking up some great memories and making lots of friends along the way,” added Foley himself. “I would like to thank the staff at Carrow Road and Colney and of course the Canary supporters for their encouragement and backing over the years.”
