JERMAINE Jenas is set for a prolonged period on the sidelines owing to an Anterior Cruciate Ligament injury sustained in training over the weekend.





Jenas, who has been sidelined with a calf complaint in recent weeks, broke down in training on Saturday after twisting his right knee when turning.





He is now set to be out of action for between six to nine months.





R’s Head of Medical Services, Dr Peter Florida, told www.qpr.co.uk: “JJ has completely ruptured his Anterior Cruciate Ligament in his right knee.





"We'll be taking him to see a specialist later this week to decide the next course of action.





"At this stage it would appear he'll require a full repair, which is likely to keep him out for between 6-9 months.”





Florida added: "JJ is in fairly good spirits all considering.





"He's been unlucky throughout his career with injuries, but he's in a positive frame of mind.





"JJ does everything asked of him in terms of injury prevention techniques – but unfortunately he’s just one of these very unlucky players when it comes to injuries.”
