Ireland lock Devin Toner admits the defending champions now face an uphill struggle to win the Six Nations title for a third year in a row.
Joe Schmidt's troops, who have only bagged one point, earned a 16-16 draw against Wales in the opening round of the Championship and went down 10-9 to France on Saturday.
"It's obviously out of our hands now," Toner told the Six Nations website.
"But there's still always a chance. Look at last year – it came down to the three final games."
Ireland have three games left to play, and all of their remaining fixtures are now must-win games if they want to stay in the running.
"The big frustration is that it's not in our control anymore," the Leinster lock added.
"The next one's going to be huge, at Twickenham where we haven't won for a while. So that's going to be massive to be honest."
Toner also eased any fears over the fitness of his second row partner Mike McCarthy after the lock was stretchered off wearing a neck brace.
Toner said: "Mike was up and walking about in the changing room, feeling quite well. He wanted to walk off the field but they wouldn't let him. He's not too bad."
