Norwich City manager Paul Lambert has confirmed Andrew Surman will be sidelined until the New Year after hurting his knee again.
Surman has only recently returned to action after three months on the sidelines and was making the second appearance of his comeback in last week's derby with Ipswich Town.
However, the midfielder took a knock to the knee in the early stages of the game before being replaced midway through the second half of the 4-1 win.
The summer signing from Wolves now faces a further few weeks out of action and Lambert confirmed that, while it is the same knee that has been injured, it is not a similar problem.
"He's going to be out for a little bit. It's a blow, but his knee's been hurt in that challenge," said Lambert. "It's not the same problem which is good but it's the same knee.
"I think he did great to go that length of time but there was just a lot of swelling overnight.
"It's hard to put a timescale on it but it's over a month anyway."
Lambert added: "I think he's been playing really, really well since he came back and it's a blow for him mentally as well, just coming back and getting hurt again.
"I've spoken to him and given him a few days off because if he keeps coming into the same environment and doing the same work when he's just done all that work to get back it's mentally hard."
