Mick McCarthy has revealed that Emmanuel Frimpong will have a scan on a suspected knee ligament injury.
The midfielder, who is on loan from Arsenal, was carried off after just 24 minutes of Wolves' 2-1 win at QPR.
The 20-year-old has started five league games for the Midlands side since joining at the start of January.
The Wolves boss fears that the injury could be a bad one but is unsure as to the extent of the injury.
McCarthy said: "He's got a brace on and he was carried off.
"On a scale of one to 10 I have got no idea. I haven't got a clue."
