USA risk all with nine changes for Australia in Women's Rugby World Cup

• Victory for Wallaroos guarantees quarter-final spot

• USA drop Alev Kelter from matchday squad

It may be only the second week of the Rugby World Cup but it is win or bust for so many teams this weekend and few games have that feeling more than the USA's showdown with Australia in York on Saturday evening.

In many ways, this is the game of the round: and perhaps the tournament so far. The two sides began in contrasting fashion but there were few surprises in that regard, with Australia racking up a record score in defeating Samoa and the United States coming up short against tournament favourites and hosts England on the opening night.
