Midfielder has an infection due to a groin injury and will miss the Reds' start to the season along with England's forthcoming friendly against the Netherlands
The infection relates to a long-standing groin injury and the midfielder is currently being treated with antibiotics in hospital
The club has issued the following statement, on their official website regarding Gerrard's condition: "Steven Gerrard today began a course of antibiotic treatment for an infection related to an ongoing groin problem.
"He is expected to remain in hospital for several days while the precautionary procedure is completed.
"The player will then return to Melwood to continue his rehabilitation programme and is expected to be available for selection in September."
The Reds captain missed a large amount of last season due to problems with his groin and his campaign ended prematurely in March as he underwent surgery.
He is now expected to miss Premier League games against Sunderland, Arsenal and Bolton for Liverpool whilst he will also now be a doubt for England's Euro 2012 qualifiers against Bulgaria and Wales which take place at the beginning of the month.
