Chelsea have been plunged into a goalkeeper crisis after it emerged that Neil Sullivan has joined number one Carlo Cudicini on the sidelines.
Cudicini is expected to be out for one month after breaking his right hand in training on Thursday.
Now back-up Sullivan been ruled out for two to three weeks with a pulled leg muscle, also suffered in training.
That means Marco Ambrosio, who has made just one, unconvincing appearance for Chelsea, will have to get his chance.
Ambrosio, who did not impress on his Carling Cup outing against Notts County earlier this season, could play in the quarter-final of the Champions League against Arsenal later this month.
Yves Makalambay, the 18-year-old signed from PSV in the summer, is manager Claudio Ranieri's only other option and he will probably be on the bench at Bolton on Saturday.
The other senior goalkeeper currently at Stamford Bridge, Jurgen Macho, is out injured for the whole of this season.
Lenny Pidgeley is on a one-year loan at Watford - although the Blues might yet try to recall him.
If the youngster - who played against Chelsea in this season's FA Cup - cannot be brought back Ranieri might seek special dispensation to sign a goalkeeper outside of the transfer window.
Czech stopper Petr Cech has already been signed for £9m from French outfit Rennes, but he does not arrive until the summer.
Meanwhile, Blues' boss Claudio Ranieri is hoping to have Argentine midfielder Juan Veron back in action within a month after a long spell out with a back injury.
"Seba is good. He could come back early next week and, in a month, he could be ready to play again," said Ranieri.
"Everything has gone right so far, with him starting to swim, run and play a little with the ball. If everything continues in this way, he could be ready in a month."
