Wolves have confirmed that midfielder Jamie O'Hara will be sidelined for at least a week with a hernia problem.
O'Hara, who missed the home defeat to Stoke at the weekend with a calf injury, will not be available for Tuesday's Premier League match with Norwich or the Boxing Day encounter at Arsenal.
Wolves manager Mick McCarthy said: "O'Hara just didn't feel right when he trained. His calf is alright actually. It's his hernia region that is the problem. He's felt it before.
"We will just have to see how he is but he's not playing against Norwich and I don't think he will be fit for Arsenal either.''
Former Tottenham midfielder O'Hara has played 14 Premier League games for Wolves this season, scoring two goals.
