Leicester City have decided against going to the Court of Arbitration for Sport in a bid to get Adrien Silva playing for them before January.
Leicester and the Football Association asked FIFA to ratify the transfer of paperwork for Silva's £22million deadline day move from Sporting Lisbon after the paperwork was submitted 14 seconds late.
But FIFA rejected the request for Silva to be registered and he cannot play for the Foxes until January.
Leicester considered an appeal to CAS over the transfer saga but have now opted against that move, and while Silva will continue training with the club he will not be able to make his debut until the New Year.
