Adam Johnson could go to jail for up to 10 years, after he was found guilty of one count of sexual activity with a minor.
The ex-Sunderland player was arrested on 2 March 2015, after he was accused of being in a relationship with a 15-year-old Sunderland supporter.
After over two weeks of deliberation the jury found the midfielder guilty of a sexual activity relating to touching.
The 28-year-old will be sentenced in two to three weeks, with the judge telling him a custodial sentence is an “almost inevitable outcome” and he will face four to 10 years in prison.
On the first day of the trial, Johnson pleaded guilty to grooming and one count of sexual activity with a child.
This led to Sunderland terminating the player’s contract with the club having previously stood by him when the arrest was first made.
In a short statement the club said: “In light of Adam Johnson’s guilty pleas, the club has today terminated his contract with immediate effect.”
