Queens Park Rangers' promotion ambitions have been hit by news that top scorer Charlie Austin faces surgery on a shoulder injury ruling him out for a "prolonged period".

The 15-goal striker suffered the problem in Tuesday's win over Bolton and after scan revealed bone, cartilage and soft tissue damage, he will now go under the knife.

QPR's head of medical services Peter Florida told the club's official website: "Charlie went for a scan on Wednesday afternoon and unfortunately it has shown he has suffered an injury to his shoulder.

"He's done some damage to the bone and cartilage in the joint, as well as the soft tissues around it, and will need an operation to correct the problem.

"We'll start his rehabilitation immediately but he's likely to be sidelined for a prolonged period."

Austin added: "I'm obviously desperately disappointed.

"Injuries are part and parcel of football but I was really enjoying my football so it's a bitter blow.

"I'll work tirelessly in my rehabilitation to make sure I return as quickly as possible and in the meantime, support the lads as we continue to push for promotion."
