Talismanic Canaries striker Grant Holt is rated as 50-50 for Friday night's Carrow Road clash against Nottingham Forest.

The City skipper is having treatment for an injury 'in the hamstring area' of his left leg, which was sustained in the closing stages of Tuesday night's 2-2 draw at Watford.

City boss Paul Lambert was, as expected, keeping his cards close to his chest at his pre-match media conference, but admitted it was a case of playing a waiting game.

'We will wait and see,' he said. 'It's minor at the minute, which is good news. Whether he is ready I will wait and see.'

The issue for Lambert is the risk involved: if he plays Holt and the problem returns, he could lose his leading scorer for the rest of the season - just when he needs him most.

'There is a balancing act,' said Lambert.

There is also a question mark over influential midfielder Wes Hoolahan, although he appears close to a return after missing the last two games with a hamstring pull.

'He looks okay at the minute,' said Lambert. 'We will see how he is today but he looks okay.'

Korey Smith is available after missing the game at Watford with an eye infection.

Lambert said he had yet to speak to Wolves boss Mick McCarthy over the future of loan striker Sam Vokes who would be vital to City's prospects if Holt were to miss games.

McCarthy has a shortage of fit strikers at Molineux and has said he intends to recall Vokes after City's trip to Ipswich next Thursday.

'Sam is Mick's player so you can't do anything when he is not your player,' said Lambert. 'That is the problem you have with loan players. I have not had the conversation with him yet.'
