"In light of Adam Johnson's guilty pleas, the club has today terminated his contract with immediate effect," Sunderland said. "The club will make no further comment."
Johnson pleaded guilty to one count of sexual activity with a child, but denied two other charges, when he appeared at Bradford Crown Court on Wednesday (local time).
The 28-year-old winger, who has played 12 times for England, also admitted one count of grooming a girl under the age of 16, a court official said.
