Devastating.

Rory Darge and Finn Russell will co-captain Scotland in this year’s Guinness Six Nations after it was confirmed centre Sione Tuipulotu will miss the entire championship through injury.

Tuipulotu will miss the tournament after sustaining a pectoral muscle injury during a training session with Glasgow Warriors last week.

He will undergo surgery this week and is expected to return to action before the end of the season.

Scott Cummings sustained an arm fracture during Glasgow Warriors match against Harlequins at the weekend. He is also likely to miss the tournament and will undergo further review to determine when he will be fit to return.

There will be no additions to the Scotland squad at this point.
