Finn Russell has joined up with the Scotland squad and has not been ruled out their Six Nations clash with France despite going off with a head injury while playing for Racing 92.
Russell went off before the break against Toulouse on Sunday and failed the initial head injury assessment.
But he was symptom-free on Monday after arriving in Edinburgh and will undergo further tests to see if he can be back playing for the national side on Saturday after the minimum six-day recovery period.
"He's with us in the training group today. Obviously it was seen that he didn't meet the criteria to return to the field of play," Scotland forwards coach Danny Wilson said.
"From now on it's an assessment process. Six days from the game is Saturday and there's a process all players go through in that period of time. We have just got to go with our experienced and outstanding medical staff."
