Burnley have suffered a major blow with the news that Ben Mee is likely to be sidelined into the new year.
The defender was injured during Sunday's local derby against Blackburn but managed to hobble on to the end of 90 minutes.
However, he was later diagnosed as having sustaining a medial ligament strain and manager Sean Dyche told the club's official website: "It's a blow for Ben.
"We will have to give the knee a chance to settle down and then fully assess the injury.
"We are hoping it will be sooner, rather than later, but we are expecting it will be weeks, rather than days."
