Back row Doris has shown symptoms of concussion and has returned to Leinster for further medical assessment. Second row Roux has returned to Connacht due to a neck problem. Both players were in contention to start for Andy Farrell's side at the Principality Stadium on Sunday.

As a result, two uncapped players - Munster backrow Gavin Coombes and Leinster second row Ryan Baird - have been called up and will train with the squad.
