Chelsea striker Fernando Torres has been ruled out of Wednesday's Champions League meeting with Schalke at Stamford Bridge.
The Spanish striker, who has been in good form of late, is suffering from what is understood to be a “muscular” problem and will also miss Saturday's match against West Brom.
"Fernando Torres is out, we need to wait for the scans on Wednesday," said Mourinho, according to the BBC. "It is easy to say he is out (against Schalke) and Saturday too."
The extent of the injury is not yet known but if scan brings bad news for Chelsea it could mean Torres will miss the rest of Chelsea's November fixtures, which include Premier League matches against West Brom and West Ham as well as a Champions League match meeting with Basel.
The absence of Torres will mean that one of either Samuel Eto'o or Demba Ba will lead the line for Mourinho's side.
"Samuel and Demba, they want to play, they want to play," Mourinho said.
"They are waiting for opportunities to play so when they have that chance, and they know they are going to have it in this game and the next game against West Brom, they know they are going to have in their hands the job to play up front. I think it has to be, a good motivation for them and hopefully they can express on the pitch the way they work during the week."
Chelsea are top of group E ahead of their clash with Schalke, who they beat 3-0 in Germany two weeks ago, but Mourinho does not want to take anything for granted.
"We are in a stable position to qualify in the Champions League but if we lose again we are in a difficult position, so Wednesday is an important game for us," he told the club's official website.
