Norwich manager Paul Lambert said the club will monitor goalkeeper Ben Alnwick after he suffered a cut to his face during Monday night's Carling Cup defeat to Sunderland.
The Canaries boss said: "Ben's face is a bit of a mess at the minute, so we just need to see how it settles down. He has got quite a bad gash under his eye. We will have to monitor him."
Lambert felt there were some positives to take from his side's 4-1 defeat to the Black Cats.
Teemu Tainio set the ball rolling for the Barclays Premier League club after 26 minutes, with Andy Reid chipping in a superb second and making it 3-0 before half-time.
Wes Hoolahan reduced the deficit just after the hour, only for Owain Tudur Jones to deflect a corner into his own net as City finished the match with only nine men after defender Michael Spillane was sent off for a professional foul on Frazier Campbell and Alnwick suffered his face injury.
Lambert said: "We started really well, and had some good chances, but when you make individual errors, especially against calibre like that, you will get punished.
"There were some positives to come out of it, and the negatives, well I have already seen them. It is not about a magic wand, it is to try to get the club up the league."
