Ross Byrne has been added to the Ireland squad for Saturday's clash with Australia as concerns grow over Johnny Sexton's availability.
While skipper Sexton was a doubt for the Wallabies clash, the fact that another out-half wasn't added to the squad when the IRFU released a lunchtime update on Monday suggested the 37-year-old was recovering well from a dead leg suffered against South Africa.
However the IRFU have now confirmed that Sexton's Leinster colleague Byrne joined the squad at their Carton House base on Monday night, which suggests Andy Farrell is making plans to cover the possibility that Sexton - nominated yesterday for the World Rugby Player of the Year award - misses out.
