Scotland flanker Alasdair Strokosch's participation in the Six Nations is in jeopardy after he sustained an eye injury during his side's 38-18 loss to England on Saturday.
The Perpignan forward had to leave the pitch in the early stages of the match at Twickenham after hurting himself in a collision and Scotland's medical staff have suggested he might miss the rest of the tournament.
"It would seem he has a fractured orbit (area around the eye) but, as ever with such collision-type injuries, they can take time to settle," said team doctor James Robson.
"He will be examined by Mr Martin Paley, a maxillary facial specialist at Spire Murrayfield Hospital on Tuesday, to determine the extent of the injury and any recovery schedule."
As well as Strokosch, fellow forwards Dougie Hall (knee), David Denton (knee) and Johnnie Beattie (ankle) will also undergo medical examinations in the coming days.
Scotland's next match is at home to Italy on Saturday.
