Wolverhampton Wanderers will be deprived of the services of Ronald Zubar for the remainder of the season after he underwent surgery.
Zubar aggravated a back problem in a win over Blackpool at the end of February and having been prevented from training properly, he has now undergone surgery to correct the problem.
Manager Mick McCarthy told the Express and Star. "Zubar has had his operation on his back and he's out for the season.
"Ronald's been an important player for us and it's a blow, but we can't do anything about it. But what about Kevin Foley? His performances have been fantastic."
Zubar, 25, has started 14 games in the Premier League this season.
McCarthy was full of praise for the form of Kevin Foley, who has regained his place in the starting line-up as a result of Zubar's injury problems.
He said: "His performances have been fantastic - we've got another top lad playing there now.''
The manager is optimistic he will have more options as the season reaches its conclusion.
McCarthy added: "Hunty and Adlene are back in training but Dave is still struggling with his back. Everyone else is fine.
"We'll maybe get a training game into Adlene at the end of the week before he plays in the reserves against Blackpool a week on Wednesday.''
