Former England footballer Adam Johnson has been found guilty at Bradford Crown Court of one count of sexual activity with a child.
The 28-year-old has previously pleaded guilty to grooming a 15-year-old girl and one charge of sexual activity with her.
Earlier he was found not guilty of one count of sexual activity with a child.
It was "totally unacceptable" Adam Johnson was not suspended from Sunderland Football Club sooner, the NSPCC has told ITV News.
The 28-year-old and his legal team met the club's chief executive Margaret Byrne in May 2015 while he was on bail, and his trial was told that during that meeting the club was made aware he had kissed the 15-year-old and exchanged messages.
He was still allowed to play for the team.
The club has denied knowing Johnson planned to admit kissing the girl.
John Cameron, head of helplines at the NSPCC, said it was unacceptable for the club to delay suspending Johnson if they knew.
"It gives a very inappropriate message, not only to the victims, but other people who are affected by this," he said.
Sunderland Football Club continued to face questions today about what they knew and when leading up to Adam Johnson's trial.
Sunderland manager Sam Allardyce says he was told that Adam Johnson would plead not guilty at this court case.
Pressure is mounting on Sunderland to explain why they played former winger Adam Johnson following his arrest.
