Liverpool goalkeeper Pepe Reina was missing for their 5-0 win over Norwich City.
Reds boss Brendan Rodgers revealed Reina, who missed the match because of a thigh injury, had an operation to repair a nose broken at Manchester United last week.
"Pepe was injured and Brad Jones came in and kept a clean sheet," he said.
"He had a thigh problem before the game last week and he played and the assessment afterwards was it had got worse - plus he had broken his nose.
"He had an operation to fix the nose yesterday so we will see how he is by next week and review it from there."
