Moody awaits medics' assessment
Lewis Moody's chances of captaining England into the Rugby World Cup will become clearer on Monday.
Moody limped out of England's 23-19 Rugby World Cup warm-up win against Wales with what he hopes is just a "tweak" of his right knee.
The England medics will assess Moody when he returns to the team's base at Pennyhill Park before any decision is taken as to whether he requires a scan.
Moody's initial fear when 18-stone team-mate Matt Banahan fell on his knee at Twickenham on Saturday was that he would miss the Rugby World Cup.
Those concerns had eased by the time Moody returned to the changing room but England still have an anxious wait before he is given the all-clear.
Moody was unlikely to play in next weekend's return match against Wales in Cardiff anyway and England will certainly take no chances with his fitness.
Johnson has Tom Wood, Chris Robshaw, James Haskell and Hendre Fourie who can also play at openside flanker in a Test match.
"Lewis is usually a quick healer," said Johnson.
"It could be one of those where he is back in a week or so and ready to play Ireland."
