Double whammy.

Ireland boss Andy Farrell has been hit with a double injury blow ahead of their Six Nations opener with Wales on Sunday.

Caelan Doris and Quinn Roux have returned to their respective provinces for further medical assessment.

Doris has flagged some symptoms that could be associated with concussion. He has returned to Leinster to allow his symptoms to be appropriately assessed and investigated.

Roux has a neck complaint that has not settled so he has returned to Connacht. Munster back-row Gavin Coombes and Leinster lock Ryan Baird will train with the Ireland squad this week.

All other squad members are expected to train this week.
