The Championship trio have been found to breach Financial Fairplay regulations.
It means that restrictions have been placed on their transfer dealings in the January transfer window and will affect them for the rest of the current campaign.
The Football League said the three clubs exceed a 'maximum deviation of £8 million' which is a £3 million operating loss and £5 million in shareholder investment during the 2013/14 campaign.
A statement on the Football League website, said: "Each club will have the opportunity to have its FFP embargo lifted at the end of the season by demonstrating that it has stayed within the maximum permitted deviation of £6m (£3m operating loss plus £3m shareholder investment) for the 2014/15 season."
The restrictions the clubs face are restrictions on signing any players for a fee unless they have fewer than 24 established players, and the players signed must cost less than £600,000 per anum.
The Football League have also said they are in discussions 'with a number of other clubs', and is considering the submissions from the three clubs promoted to the Premier League last season in Leicester City, Burnley and Queens Park Rangers.
