Reds boss Rafa Benitez has confirmed he will be without Torres, Alvaro Arbeloa and Daniel Agger for the Black Cats game, but is hopeful Gerrard will be fit to start.
"Stevie was OK and will hopefully be available tomorrow," Benitez told the club's official website.
"Torres is not ready yet. We have to wait to see how he progresses but he won't be in the squad.
"Arbeloa has a problem with his hamstring. He's had the problem before. It could be another week."
