Scott Murray will face an independent disciplinary hearing in London on Wednesday after his red card in Scotland's RBS 6 Nations Championship defeat to Wales.
Murray was given his marching orders just 22 minutes into Scotland's 28-18 defeat after he retaliated to a late tackle from Ian Gough by lashing out with his boot and catching the Wales lock in the face.
The former Scotland captain apologised immediately and shook hands with Gough on the field.
Murray's remorse will no doubt be taken into consideration by the panel, but under International Rugby Board guidelines he faces a ban of up to 12 months.
The panel will comprise of chairman Paul Mauriac (France), Peter Boyle and Dr Barry O'Driscoll (both Ireland).
As head coach Stuart Lancaster polishes the axe he will soon wield over his World Cup training squad, Exeter Chiefs coach Rob Baxter has backed Jack Nowell, Henry Slade and Luke Cowan-Dickie to be given a stay of execution.
Italy Under-20s held off a late Samoa blitz to retain their place in the World Rugby U20 Championship on Saturday and head coach Alessandro Troncon believes the experience will have served as a valuable lesson for his young troops.
