The Black Cats saw their relegation fears deepen at Carrow Road as they were comfortably beaten by the Canaries.
"Of course we're disappointed with the result; it was a big game," Bridcutt told the club's official website.
"It turned out to be tougher than we expected; it was one of those days for us, nothing went our way and Norwich were at us from the get-go.
"I'm sorry for the fans who made the trip to Norwich; it's a long, long way from Sunderland and they deserved much more than that."
Sunderland continue their battle for survival on Wednesday when they travel to title challengers Liverpool.
