Co-hosts New Zealand are 90 minutes away from a historic first at the Women's World Cup, no matter what the result when they take on Switzerland in their final group game on Sunday (live on RTÉ2 and RTÉ Player).
Since the first edition in 1991, the hosts have always qualified for the knockout stages and New Zealand will advance if they win. Qualification will also mark the first time in six attempts they have reached the knockouts.
But with three points separating table toppers Switzerland and bottom side Norway, all four teams have a shot at qualifying for the last 16.
Tie-breaking criteria - starting with goal difference - may come into play if New Zealand draw, depending on Norway's result against the Philippines (live on RTÉ News and RTÉ Player), while a loss will definitely see the Football Ferns eliminated.
Norway, however, will be without injured striker Ada Hegerberg after the Ballon d'Or winner failed to recover in time from a groin injury that saw her withdraw from the previous game before kick-off.
England midfielder Keira Walsh's World Cup hangs in the balance after a scan revealed she did not suffer an anterior cruciate ligament injury in the 1-0 victory over Denmark on Friday.
The 26-year-old will definitely miss the Lionesses’ final group-stage clash with China on Tuesday but will remain in Australia as she undergoes further medical assessments.
Germany and Colombia are top of Group H with three points each ahead of their clash on Sunday and the European side's quest for a third title was dealt another blow when they lost a third defender to injury.
Full back Felicitas Rauch suffered a knee injury in training to join Giulia Gwinn and Carolin Simon on the sidelines but coach Martina Voss-Tecklenburg believes others will step up.
"We know what type of backup options we have... We take some strength from that," she said.
"We want to basically be in that mindset where it doesn't matter who's standing there on the actual pitch."
Colombia had their own scare when teenage striker Linda Caicedo collapsed in training but coach Nelson Abadia said the 18-year-old, who became the youngest player to score in the tournament, is fine.
"She was tired. She was a bit stressed as well, because she was playing in her first World Cup," Abadia said.
"It was just an episode, it's finished, it's over. We're quite happy about this, no problem."
