QPR defender Peter Ramage could miss the rest of the season with a cruciate injury.
The 26-year-old former Newcastle full-back fell awkwardly during Saturday's win over Middlesbrough and is set to undergo surgery.
"Peter will have to have an operation on his cruciate ligament and unfortunately it looks as though that's him for the season," said Rangers boss Neil Warnock.
"I feel so sorry for him, he's an important part of the squad. It's disappointing for the lad, he's distraught but he'll bounce back."
