Torres hobbled off after 11 minutes and boss Jose Mourinho confirmed he won't be available to link up with Spain next week.
The striker is suspended for Chelsea's trip to Norwich on Sunday and will be looked at by experts today.
Mourinho said: "It's something in his knee, his ligament, and we have to wait for the scan.
"The doctor is very confident it's not a big injury, like we had with Marco van Ginkel (who is out for six months).



    
"He knows that he doesn't play against Norwich. He knows that he cannot go to the national team.
"He knows he has 15 days until the next match he can play, which is against Cardiff.
"Let's see the scan. If the injury is an injury for 15 days, I think he'll be fine. That's okay.
"The problem is if it's more time and it's a pity for the guy, because he's in a very good moment."
