Leicester have dropped their plans to appeal Adrien Silva's banned transfer from Sporting Lisbon.

FIFA rejected the transfer after they received the documents 14 seconds after the transfer window had closed.

The Foxes had originally planned to appeal the decision through the Court of Arbitration for Sport, but the Sun reports that FIFA had told them they would be wasting their time.

World football's governing body told the Premier League club that they would not fast track the appeal, which would mean it could be heard as far away as January - when Silva can sign for Leicester anyway.

A Leicester statement read: "It was our intention to submit an application to the Court of Arbitration for Sport for expedited proceedings so that the matter could be resolved as quickly as possible.

"However, it has been made clear to us that Fifa will not support an expedited process, forcing the club to reluctantly accept the single-judge ruling of Fifa's Players' Status Committee without reasonable opportunity for independent arbitration that is timely enough to be effective.

"Our frustration at the denial of effective due process doubles our disappointment at the original outcome and while the club is now essentially powerless to continue to challenge the decision, we will continue to support Adrien in any personal appeal he wishes to undertake.

"We intend to register Adrien at the earliest opportunity. In the meantime, he will remain under our care, training with the squad under the supervision of our coaching, medical and sport science staff."
