Scunthorpe say defender Rob Jones's injury is not as bad as was feared after he collided with a goalpost in Saturday's game at Sheffield Wednesday.Jones was stretchered off in a neck brace and taken to hospital.
However, the club say he has been released from hospital after treatment for concussion.
Meanwhile, newspaper reports in Scotland have linked the Iron with a £200,000 move for Jones' old team-mate Colin Nish of Hibernian.
Speaking about Jones's condition, Iron boss Nigel Adkins told BBC Radio Humberside: "He had a CT scan after the game in the hospital in Sheffield and he's been diagnosed with concussion, there's no fractures or anything in there.
"He came back on the bus with us and he's been in work this morning but you can still see that he's still visibly shaken and he's still groggy.
"He's seen the doctor today and he just needs a quiet few days to settle down and that means he's in jeopardy of not been available for the game against QPR [on Saturday].
"He'll definitely miss the Swansea game [on Tuesday] and he's not travelled with us."
