Ireland wing Simon Zebo has been ruled out for up to ten weeks with a broken bone in his foot, coach Declan Kidney has confirmed.
Zebo was helped from the field in the early minutes of Ireland's RBS 6 Nations clash with England at the Aviva Stadium on Sunday.
Ireland's outhalf Jonathan Sexton was also helped from the field when he appeared to pull a hamstring as he flykicked the ball forward.
It is believed that Sexton has suffered a hamstring tear and will also be out for two weeks. It that proves correct, he will miss Ireland's next Six Nations clash with Scotland at Murrayfield on 24 February.
Flanker Sean O'Brien (tight hamstring), second rows Mike McCarthy (knee ligament strain), Donnacha Ryan (back) and centre Brian O'Driscoll (twisted ankle) are all injury worries. Their fitness situations will be monitored in the coming weeks.
Ireland head coach Declan Kidney has said: "Simon [Zebo] will have surgery.
"Jonny [Sexton] will have a scan either later tonight (Sunday) or tomorrow.
"It looks like a couple of weeks for Jonny, but it would be wrong to try and second guess the outcome. We'll know more by Tuesday.
"It's been an attritional couple of games and we had a few injuries leading into the tournament, but that's the way it goes."
