|Coverage: Live on ITV, BBC Radio 5 live sports extra, BBC Sport website and BBC Sport app, plus live text commentary.|
Scotland lock Jonny Gray and back-row forward David Denton have been ruled out of Saturday's Six Nations match against Ireland in Dublin.
A scan showed Gray had partially torn a pectoral muscle while Denton, 26, sustained a groin injury before last month's 36-20 defeat of Italy.
Russell was withdrawn early against France after suffering a concussion.
He is undergoing the graduated return-to-play protocol.
