Liverpool will recall goalkeeper Peter Gulacsi from his loan spell at Hull City after finding out they will not be allowed to sign a keeper on loan.
The Merseyside club face Everton in Saturday’s FA Cup semi-final.
With Pepe Reina and Alexander Doni serving bans, manager Kenny Dalglish had hinted he wanted to bring in cover for third-choice Brad Jones.
But Premier League regulations only allow a move when injury, rather than suspension, affects a squad.
Hungarian 21-year-old Gulacsi was on a season-long loan at Hull but failed to regain his place following a knee injury and has not played since New Year’s Eve.
He has never played for the Reds first team and has had loan spells at Hereford and Tranmere.
The untried Danny Ward, 18, or 17-year-old Tyrell Belford had also been in contention to be named as substitute at Wembley.
Reina is serving a three-match ban for his dismissal in the defeat by Newcastle United while reserve goalkeeper Doni is banned after being sent off in Tuesday’s 3-2 win at Blackburn Rovers.
Dalglish insisted he had “no problem whatsoever” with the prospect of selecting Australian Jones, who has made just three appearances since signing for £2.3m from Middlesbrough in August 2010.
