Liverpool goalkeeper Alexander Doni will miss Saturday's FA Cup semi-final against Everton at Wembley after the Football Association rejected an appeal over his red card at Blackburn.
Doni was dismissed during Tuesday's 3-2 win at Ewood Park for bringing down Rovers midfielder Junior Hoilett.
The decision means that the Brazilian's one-match ban stands.
First-choice keeper Pepe Reina is already suspended, leaving third-choice Brad Jones as the most likely option.
Jones came on in the 26th minute of the game after Doni's dismissal and immediately saved Yakubu's penalty.
He was later shown a yellow card after conceding a penalty of his own, which Yakubu scored.
The Merseyside club have already recalled goalkeeper Peter Gulacsi from his loan spell at Hull City after finding out they were not allowed to sign a keeper on loan.
The 21-year-old Hungarian 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 previous loan spells at Hereford and Tranmere.
The disruption caused to Liverpool's semi-final preparations has been considerable, but Jamie Carragher insists the problems which have beset such a key position will not derail their hopes of reaching the final at Everton's expense.
"It's not ideal, of course, but it's just one of those things that happens," Carragher said.
"I think losing Pepe was the blow if you like. Whether your third-choice or second-choice keeper plays, I don't think there's that much difference between them really."
