The striker has pulled out of the Uruguay squad, preparing for Friday night's match against Estonia and next Tuesday's friendly with the Republic of Ireland, due to a back problem.
The injury is not as bad as first thought and he feels he should be okay to play against Roy Hodgson's men.
He said on his Twitter page: "In Liverpool working hard to be ready for next match.
"I've been lucky, the injury isn't that bad and it should be fine. I also want to tell you I'm a bit sad for not playing the match with Uruguay."
