QPR defender Anton Ferdinand is facing a fortnight of rehabilitation after suffering a hamstring injury, according to manager Neil Warnock.
The centre-back sustained the problem in the second half of his side's defeat at Liverpool on Saturday and had to be substituted.
Warnock estimates Ferdinand is going to require at least 14 days to recover, but the QPR boss hopes Matthew Connolly (ankle) or Fitz Hall (hamstring) could return to provide cover.
"It will probably be a couple of weeks and it opens the door for Matthew Connolly or Fitz Hall, who would be fit next week," said Warnock.
Warnock also calmed fears surrounding the absence of Heidar Helguson at Anfield amid reports the in-form striker was either ill or injured.
The decision had been taken to rest the Icelander, who has scored six goals in his last seven games, and he will return for next Sunday's match against Manchester United at Loftus Road.
"It was squad rotation with Heidar; if he played yesterday there was a risk of him missing two to three weeks," he said.
"It was only a minor thing and if it had been the last game of the season he would have played but he will be all right for next week."
