Finn Russell will not feature in Scotland's Six Nations opener against Ireland after being sent home for disciplinary reasons.
Scottish Rugby announced on Thursday that Racing 92 fly-half Russell has been released from Gregor Townsend's squad for a breach of team protocol.
Scotland will have to do without Russell at the Aviva Stadium a week on Saturday and it remains to be seen if he will play any part in the tournament.
A Scotland team spokesperson said: “Stand-off Finn Russell will play no further part in preparations for Scotland's Six Nations opener against Ireland, having been disciplined for a breach of team protocol during the week's camp in Edinburgh.
"He has returned to his club."
Russell last year revealed he had a disagreement with head coach Townsend after a dramatic 38-38 draw with England at Twickenham.
"I actually had an argument with Gregor [at half-time]," Russell told ITV after the game.
"I said to him, 'You're telling us to kick and when we kick, they just run it back and cut us open, and when we run it, they're just hitting us behind the gain line and winning the ball back'.
"Second half, we just came out with nothing to lose, played our rugby, kicked out of our half and scored some great tries. We played good Scottish rugby."
The 27-year-old played at Glasgow Warriors from 2012 to 2018 before landing his move to France.
