The Rugby League World Cup is played every 5 years, and this year is being hosted by England and Ireland.
The US finished on top of their group, which now gives them the right to play the winner of Group A, which is Australia.
To get to this point of the tournament, Australia beat England in the opening game 28-20, smashed Fiji 34-2 and destroyed Ireland 50-0.
The USA Tomahawks won through by beating Cook Islands 32-20, shocked Wales 24-16 and with that, was enough to see them qualify, then lost to Scotland 22-8.
That now sees the winner of Group A (Australia) play the winner of Group D (USA) in the 2nd Quarter Final. The winner then plays the winner of the Samoa v Fiji QF.
For anyone interested, and if you can access it on TV, the game is scheduled to start at 1pm (England time), with the game being played at Wrexham. That means it will be played at 11.30pm Saturday, Australian time, which would be about 9.30am Saturday morning US (West Coast) time.
