Scotland centre Marcus Di Rollo faces a race against time to be fit for the trip to Wales on Sunday after the RBS 6 Nations Championship win over France at Murrayfield.
The Edinburgh Gunners player picked up a hamstring injury in the 29th minute of the surprise 20-16 triumph.
But Scotland team doctor James Robson is not rushing into a decision on the 27-year-old.
He said: "Marcus has a sore hamstring and he is being looked after by our physios. We are not making any decision on him just now."
