Thanks to Nigeria's upset win, Canada finds itself in Women's World Cup logjam

After a wild night in Perth, the Canadian women's soccer team returned to its training base in Melbourne on Thursday to prepare for a crucial match against Australia at the FIFA Women's World Cup.

Hours after landing, seventh-ranked Canada found itself in a Group B logjam thanks to No. 40 Nigeria's 3-2 upset win over No. 10 Australia in the final game of the day.

With one round of games remaining, it's all up for grabs in Group B. Olympic champion Canada could finish first or second, booking its ticket to the round of 16, or place third and head home early.

In the final group games Monday, it's Canada versus Australia in Melbourne and Nigeria versus Ireland in Brisbane.

Australia has to beat Canada to move on. The Canadians can advance with a draw or win.

Canada could still move on with a defeat — as long as Nigeria also loses and the final goal difference favours the Canadians.

The team that finishes atop Group B will avoid the winner of Group D, expected to be either No. 4 England or No. 13 Denmark, in the round of 16. The Group B runner-up faces the Group D winner.

But just surviving the opening round is the immediate task at hand.

Canada is coming off a 2-1 comeback win over Ireland on a wet miserable evening Wednesday. The Canadians rebounded from a subpar performance in the first half, looking shell-shocked after conceding a fourth-minute Olimpico goal by Irish star Katie McCabe off a corner.
