The former Sunderland winger and England international was sentenced at Bradford Crown Court after being found guilty of one count of sexual activity with a 15-year-old girl.
Adam Johnson has lodged an appeal against his six-year prison sentence.
The former Sunderland and England winger was sentenced last month at Bradford Crown Court having been found guilty by a jury of one charge of sexual activity with a 15-year-old girl.
Johnson, who had already pleaded guilty to a lesser charge and one of grooming, has already begun an appeal against that conviction.
An official at Bradford Crown Court confirmed to Omnisport that the 28-year-old has now applied for a review of his six-year prison sentence.
