Liverpool skipper Steven Gerrard is unsure if teammate Luis Suarez will make Uruguay's World Cup squad.
Uruguay's team doctor remains cautiously optimistic about Suarez making the tournament, while Liverpool team-mates Jordan Henderson and Glen Johnson have done some investigative work as to the severity of the injury.
"I don't know whether he is going to be available," the England captain said.
"I think the only people that know whether he is going to be available is Luis himself and the physio and doctors in their team.
"For me, it is not very important, it is something we can't control and is not my main focus. My main focus is to make sure all the England players are fit and available to play.
"Going into that game we're very confident that we can get the right result whether Luis is available or not."
