Frank Lampard will miss England’s crucial Euro 2008 qualifier with Israel on Saturday – and is rated 50-50 to face Russia four days later.
Lampard, 29, tore a thigh muscle in training with Chelsea last week and has returned to his club to undergo treatment.
“Frank came and joined us last night, we looked at the scans and have liaised with Chelsea,” said England coach Steve McClaren.
“He’s gone back there for rehab – the injury is not as serious as we first thought, although hopefully we’ll assess him on Saturday.
“He may be 50-50 for next week – and Chelsea are giving him every chance of being available for us.”
McClaren was more optimistic about Steven Gerrard’s chances of recovering from a toe injury in time to face Isarael.
Gerrard has assured McClaren he will be fit for England’s crucial double-header.
“All being well Stevie will be available on Saturday,” added McClaren.
“I want him to play, the team do, the fans do and so does the whole country. We need big players and Stevie is one for us.
“We’re assessing it day by day. He’s getting better and hopefully by the end of the week we’ll have a better idea.”
