Ireland topped Pool D with a hard-fought 24-9 win over France, in a battle between two previously unbeaten sides at the 2015 Rugby World Cup.
Second-half tries from Rob Kearney and Conor Murray made the difference for Ireland, who will now face Argentina in the quarter-finals, with the defeated French set to face New Zealand.
The win was crucial for the Irish, but it came at a cost with a number of injuries which may ruin their chances of further success at this World Cup.
Paul O'Connell looks set to miss the rest of the competition with a serious hamstring injury, whilst Peter O'Mahony and Jonny Sexton also left the field and are doubts ahead of the knockout stages.
The news for the Irish could also get worse, with Sean O'Brien almost certain to be cited for a sucker-punch to Pascal Pape's ribs in the early stages of the game which went unnoticed at the time.
Irish take half-time lead after kicking duel
The only first-half points came via penalties in a tight affair dominated by the two defences.
After a pair of French misses, Sexton got the first points of the day after slotting a regulation penalty from inside the French half.
France's Scott Spedding then equalled the scores with a long-ranger, with the South-African born full-back trading three-pointers with Sexton to see the sides level at 6-6.
Ian Madigan took over as the Irish kicker and gave his side a 9-6 lead, with Sexton having to leave the field after taking a number of blows to his ribs.
Henderson eases fears after joining game at half-time
On the cusp of half-time, Irish captain Paul O'Connell was in agony and had to be carted from the field and suffering a severe hamstring injury, with Ian Henderson taking place in the lineup.
The Ulsterman was unfortunate to lose his place to Devin Toner in the first place, and played like a man-possessed in the second-half as Ireland took control of Pool D.
A Rob Kearney try in the 50th minute was followed by Conor Murray's effort with eight minutes remaining as the Irish took control after the break.
Joe Schmidt and the Irish nation will be hopeful this week that injuries to O'Connell, Sexton and O'Mahony aren't tournament ending, with the possible O'Brien citing another cause for concern over the next few days.
For France, a strong first-half had set them up perfectly for a tournament-defining win but it wasn't to be, and they will now face the world's best side in a repeat of the famous 2007 World Cup quarter-final at the same stadium, which of course they won thanks to an inspired performance from Freddie Michalak. It will be an interesting week for both sides.
