Leicester City have been charged by the Premier League with allegedly breaking spending rules during their last three seasons in the top flight.
Leicester have been referred to an independent commission for breaching profit and sustainability rules (PSR) and failing to submit audited finances.
If found guilty the Championship high-flyers could face a points deduction.
The Foxes are also subject to a separate financial probe by the English Football League (EFL).
Leicester, who were relegated at the end of last season, said they were “surprised” and “disappointed” by the timing of the Premier League’s actions, when the club is not in the top flight.
The club added they would “defend” themselves “from any unlawful acts by the football authorities, should they seek to exercise jurisdiction where they cannot do so”.
