Liverpool striker Fernando Torres has now been revealed as a major doubt for their derby after the international break against Everton.
It was confirmed that the Spanish international striker had strained an adductor muscle – a similar injury to the one he sustained in the World Cup final.
Fernando Torres had to be substituted out after just 10 minutes of the 2-1 defeat to Blackpool at Anfield on Sunday.
Manager Roy Hodgson said the 26-year-old had strained his groin but did not know the severity of the injury.
“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 October 17, is hugely significant with Liverpool currently wallowing in 18th place in the Premier League after their worst start to a campaign since 1953-54, when they were relegated.
