Ulster pair Tommy Bowe and Chris Henry are injury doubts for Ireland's autumn series clash with Australia at Dublin's Aviva stadium on Saturday.
And despite fullsome praise for their Ravenhill team-mate Paddy Jackson, from new Ireland coach Joe Schmidt, after the weekend 40-9 win over Samoa, the young Ulster player could make way for the return from injury of experienced Lion Johnny Sexton.
Sexton is expected to resume training today after a hip injury.
Bowe emerged as an injury doubt after feeling a tightness in his lower leg after coming off during the second half against Samoa and was later using crutches, while Henry is rated as a major doubt after suffering a suspected hamstring tear.
The full extent of their injuries will become known today. Otherwise, the medical bulletin looks positive for Schmidt.
Captain Paul O'Connell, Brian O'Driscoll, Sean O'Brien, Cian Healy and Mike Ross all came through unscathed after recent injuries, while debutants Jack McGrath and two-try hero Dave Kearney made strong first impressions.
