Norwich City boss Paul Lambert will decide this week whether to try to bring in another goalkeeper after confirming that Declan Rudd will be out for two months because of an ankle injury.

Rudd, who celebrates his 21st birthday today, played in the 4-1 FA Cup win over Burnley nine days ago, but with John Ruddy back in the senior side for Saturday's 2-1 Premier League win at West Bromwich Albion, it was instead 19-year-old Jed Steer on the bench as back-up.

Lambert explained after the game: 'Dec's hurt his ankle, and will be out for couple of months.'

Asked if that meant an operation, he added: 'It looks like that.'

The City boss will discuss with his assistant manager and goalkeeping coach whether they need another senior 'keeper.

'I need to sit down with Ian Culverhouse and Jeff Wood and decide what we're going to do, but if push comes to shove, I wouldn't have any fear about Jed whatever,' said Lambert.

'I don't think there is much between him and Dec as it is but I'll sit down with the lads and have a discussion about it.'

Lambert, meanwhile, was delighted with a second successive away win thanks to goals from Andrew Surman and Steve Morison.

'It's an absolutely fantastic result away from home, back-to-back winning at QPR and here, and I thought the lads were excellent,' he said.

'They defended really strongly when they had to.

'The lads put their bodies on the line and counter-attacked really quickly, which was great.

'The crowd here are really passionate, they get right behind their team and they make it difficult for you.

'I think the important thing was we never capitulated at 1-1, when it's easy to do when a team has got a foothold in the game. As long as the lads stay in the game you get chances.'

Both goals were swift counter-attacking moves, with Surman volleying in Wes Hoolahan's cross and Morison heading home from substitute Grant Holt's centre.

'For the first goal, Simeon (Jackson) made a great run and Pilkington found him. Hoolahan provided the cross, but you've still got to finish it. Surman did it terrifically well,' said Lambert.

'He's a really brilliant footballer, Andrew Surman.

'A really clever, intelligent footballer and I think at this minute he's playing as well as he has done.

'For the second one, Holty did fantastic for us and what a header from Morison, because he still had to get above a defender and beat the goalkeeper. I'm delighted – absolutely delighted.

'John Ruddy was on top of his game and great credit to the lads for the way they defended.'

After 21 Premier League games, City still have yet to keep a clean sheet – Shane Long's penalty for Albion denying them that achievement – but Lambert is not worried.

'It would be nice to walk away with a clean sheet as the lads are desperate for it, but we're winning games,' he said.
