Colchester midfielder David Fox has joined Norwich on a two-year deal for an undisclosed fee.
The move will see the ex-Manchester United trainee reunited with former boss Paul Lambert, who signed the 26-year-old from Blackpool last summer while in charge of the Us.
Lambert told the club's official website: "I signed him at Colchester last year and he had a brilliant start to the season.
"He's someone who will hopefully benefit the team with his wide range of passing and I'm delighted to be bringing him to Carrow Road."
Colchester chairman Robbie Cowling told Colchester's official website: "David came to us and explained that he and his family had never really settled in the area so we agreed that if another club came in for him, we would consider letting him go.
"We got him on a free contract 12 months ago and now Norwich have offered a fee for him. It is not productive to have unhappy players here at Colchester United and it was in our and David's best interests that he moved on."
