Rafael Benitez was hoping his star striker would be fit for today's trip to Ewood Park after Torres resumed full training this week. However, he is not yet fully fit and so won't be risked.
"He has been training with the team - not full training sessions but part of them. He's doing well but he will not be ready for this game," said Benitez.
"He could be ready for Fiorentina. He was doing some exercises with the team and with the football but it's too soon.
"Maybe next week it will be easier."
