Adidas have terminated their contract with Adam Johnson after the Sunderland winger pleaded guilty to grooming and sexual activity with a child.
Johnson has denied two further charges of sexual activity and will go on trial on Friday. The former England winger was arrested at his home in March last year.
Sunderland manager Sam Allardyce confirmed on Thursday that Johnson would not be in the squad for Saturday's match with Manchester United.
And Adidas have now released a statement which read: "Adidas can confirm that it has terminated its contract with footballer Adam Johnson with immediate effect.
"This follows his guilty pleas entered earlier this week."
Allardyce was terse when asked about Johnson's situation at his press conference on Thursday afternoon, although he did say that the player would not be part of his squad this weekend.
Asked if Johnson's absence would extend beyond that, with the trial at Bradford Crown Court scheduled to last more than two weeks, the Black Cats boss added: "We will see how it goes after that."
