Liverpool's Fernando Torres is a doubt for the Merseyside derby after straining an adductor muscle.
The Spain striker limped off after just 10 minutes of the 2-1 defeat to Blackpool at Anfield on Sunday with a similar injury to the one he sustained in the World Cup final.
Manager Roy Hodgson said the 26-year-old had strained his groin but did not know the severity of the injury.
Torres pulled out of Spain's squad for the forthcoming Euro 2012 qualifiers against Lithuania and Scotland and had a scan at the club's Melwood training ground.
"Fernando was assessed earlier today at Melwood and underwent a scan this afternoon," said Dr Peter Brukner, head of sports medicine and sports science.
"He will have intensive treatment over the next couple of weeks but it is too early to say if he will be fit for the game against Everton."
The derby, at Goodison Park on 17th October, is hugely significant with Liverpool currently wallowing in 18th place in the Barclays Premier League after their worst start to a campaign since 1953-54, when they were relegated.
Everton have also had their difficulties in the current campaign and are just one place above their near-neighbours, on goal difference alone.
The two clubs below them are West Ham United and Wolverhampton Wanderers who meet at Molineux the previous day. Victory for either side would mean both Merseyside rivals would be in the bottom three when they lock horns at Goodison Park.
