Wales v Lebanon
by BBC Sport
Victory in both matches is Wales' final chance to make the Rugby League World Cup in Australia in 2008.
Coach Martin Hall's side have a 100% record in 2007, but Sunday's win over Scotland was not enough to overturn a deficit from last year's game in Wales.
"I've never seen a dressing room so low," said assistant coach Kevin Ellis.
Who will claim the final World Cup spot?
"We felt we let ourselves down and it was our mistakes that cost us automatic qualification.
"We just have to learn from that game and we need to get all the negativity out of us and think of the positives, which are we won the game and we're still unbeaten this year."
Celtic Crusaders' new signing Mark Lennon will miss the game, a hamstring injury picked up in the win over Papua New Guinea expected to rule him out until next month.
Lee Briers (ankle) is the major new injury worry, with Ian Webster also carrying a knock.
Wales and Lebanon have met just once before at full international level, in the 2000 World Cup where Wales won 24-22 in Llanelli, Lebanon's last defeat.
Lebanon are missing some of their big names, including injured Sydney Bulldogs star Hazem El Masri, the top points scorer in NRL history with 2,040 points, and Robbie Farah, who Wests Tigers have refused to release.
Penrith Panthers' Hassan Saleh, Wests Tigers' Allen Soultan and Sydney Bulls' Charlie Nohra have all been sent back to Australia with injuries, while seven other players from the 16-16 draw with Ireland last Friday are having treatment.
The winners of the semi-final matches will compete at Featherstone Rovers' Chris Moyles Stadium on Wednesday, 14 November for the 10th and final World Cup spot.
