Liverpool captain Steven Gerrard will be out of action for three weeks after having a scan on his injured hamstring according to reports.
Gerrard was replaced after 16 minutes of Wednesday's FA Cup replay against Everton, which Liverpool lost 1-0.
The midfielder will now miss Saturday's match against Portsmouth, England's friendly against Spain next week and the visit of Manchester City.
Gerrard, 28, also faces a race against time to be fit for the Champions League tie against Real Madrid on 25 February.
