Northampton Saints' Alex Corbisiero is a doubt ahead of England's clash with the All Blacks on Saturday.
Corbisiero faces a key training session later this afternoon that should determine his availability to face New Zealand at Twickenham as he continues his comeback from a knee problem.
"We're monitoring Alex now. He's normally a one session per game player, especially on a Tuesday when we do two heavy sessions," forwards coach Graham Rowntree said.
"We'll know more after we've monitored him this afternoon. As far as I'm concerned we're still as we are for the weekend."
The Northampton prop completed a routine meeting with a specialist on Monday night after playing the second half of last Saturday's victory over Argentina.
Rowntree said: "It's nothing out of the ordinary, it's part of his knee management in conjunction with Northampton and our team physios."
