Fly-half Finn Russell has left the Scotland Six Nations training camp following a “breach of team protocol”.
Gregor Townsend’s side face Ireland in Dublin on February 1st, but could now be without arguably their most influential player.
A statement from a Scottish Rugby spokesperson read: “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.”
There has been no comment on whether Russell, who has accrued 46 caps for Scotland since making his debut in 2014, could rejoin the squad after the Ireland clash.
