QPR defender Jake Bidwell appears to be facing a lengthy spell on the sidelines after being taken off injured against Derby.
Bidwell was led away after half an hour of the game at Loftus Road with what initially appeared to be a shoulder injury, although Rangers fear he may have suffered a fractured collarbone.
The former Brentford man was taken to hospital and Rangers are awaiting news on his condition.
“He’s gone to hospital. It didn’t look good. Shoulder or collarbone – we don’t quite know yet,” said Steve McClaren.
Rangers boss McClaren praised his side after Geoff Cameron’s equaliser secured a 1-1 draw.
Jack Mariott had capitalised on an error by Toni Leistner to put Derby ahead midway through the second half.
Cameron’s goal was his first since arriving at QPR on loan from Stoke and only the American’s third goal in English football.
“We were disappointed with the goal we conceded and said that we had to show character in the second half,” said McClaren.
“It was a big second half for us. We scored early and didn’t settle for that and nor did Derby.We went for it and they did.”
Meanwhile, Derby boss Frank Lampard insisted QPR were gifted a point by a poor refereeing decision.
