Wolverhampton Wanderers will be without the services of defender Ronald Zubar for more than a month because of injury.
Zubar injured his knee during Wolves' 1-1 away draw with Arsenal in the Premier League on Tuesday and will spend between four to six weeks on the sidelines.
Wolves manager Mick McCarthy revealed the extent of the injury of the Frenchman on Friday ahead of his side's game at Bolton Wanderers in the league.
"Ronald is injured and could be out for a month although we hope that's not the case because he's been playing really well," he said on Wolves' official website.
"They're saying four to six weeks but hopefully it will be three.
"They may be able to inject it to help speed it up."
