Scotland captain Jason White could miss the Six Nations after sustaining a knee injury during the win against Romania.
White, 28, has already been ruled out of next Saturday's match against the Pacific Islands and is set to consult a specialist to determine the extent of the injury.
But Scotland coach Frank Hadden has already admitted to fears his skipper is set for a lengthy spell on the sidelines.
He said: "Jason is still to be seen by the specialist, but it appears that he may be out for some considerable time.
"I don't think we'll know for certain about the Six Nations until the specialist has had a look, but the initial reaction is that he will be out for some time."
The loss of White may open the door for Simon Taylor to make his return to international colours against the Pacific Islands.
Taylor underwent a knee reconstruction towards the end of last season and made his comeback last Friday, playing an hour of Edinburgh's match against Newport-Gwent Dragons.
"I watched that game with interest on Friday night, and obviously we have monitored Simon's progress with interest," said Hadden.
"He has trained with us all season, and his rehab has gone extremely well, so he is definitely an option we are considering for the weekend.
"Obviously, our medical team have been working with him for a long time, and are happy with where he is at the moment, but there is no way would take a gamble.
"We will be discussing what the next step for Simon is, in terms of what is best for him and what is best for everyone else."
Hadden intends to name his starting XV for the Pacific Islands match on Tuesday.
