The Liverpool captain is out of the England squad for this week's friendly against Germany after picking up an injury in Saturday's win over Bolton. Gerrard is also a doubt for the home game against Fulham next Saturday.
"Steven picked up an injury in yesterday's game at Bolton," said press spokesman Ian Cotton.
"A scan this morning has confirmed a tear in the adductor magnus muscle in his right leg, and he is expected to be out between seven to 10 days."
