Gerrard immediately signalled to be substituted after feeling his groin during Liverpool's 4-1 win over West Ham on Saturday.
According to the Liverpool Echo, Gerrard faces a prolonged spell on the sidelines after the extent of the injury was confirmed by scans this morning.
The news comes as a blow to Brendan Rodgers and Liverpool, who will be without their influential skipper for the busy festive period.
Liverpool take on Tottenham at White Hart Lane on Sunday, and could also be without Jordan Henderson, who left Anfield in a protective boot following the win against the Hammers.
Despite the absence of two key players, Rodgers says he is confident that Liverpool will not falter as they continue their pursuit of a top four finish.
"Steven is such an important player for us, but we have other players and dynamics in the team and they have to step up," he told reporters.
Lucas has been excellent for us and he has forced his way into the Brazil side, so he has that quality and experience to step up and take the responsibility.
"Joe looks like he did when he first came here with his movement, his body work and fluency on the ball and that's what we need right now. We have a number of small players on the field but if we have the ball and the other team hasn't, I think they struggle with it.
"We need that mobility and constant movement in the midfield to get on the ball and knit the game together."
Liverpool currently sit in 2nd in the Premier League, three points ahead of Spurs in 6th.
