Steven Gerrard will be out for a fortnight with a hamstring strain and Yossi Benayoun will be out for a month with a fractured rib.
A spokesman told the club’s official website: “Steven Gerrard and Fernando Torres both underwent scans earlier today after coming off in the FA Cup tie against Reading.
“Steven has a hamstring strain and will be out for a fortnight, while Fernando has torn a cartilage in his right knee. The injury will require surgery and he is expected to be sidelined for six weeks.
“Yossi Benayoun also suffered a fractured rib in the game and will be unavailable for between three and four weeks.”
