Danny Brough and Matty Smith will form a new-look half back pairing as McNamara looks to blood fresh players ahead of the Rugby League World Cup next season. Stefan Ratchford and Scott Taylor are also England debutants, with Ratchford starting at full back while Taylor is expected to come off the bench.
McNamara says the partnership of Smith and Brough excites him.
He said: ““They have been in tremendous form in the Super League and I know they have the ability to step up and perform at this level. They will complement each other’s skills and can form a devastating partnership.
“We have made a number of changes from the first game and it is an exciting opportunity to see some real quality young players coming in and staking a claim for a regular place in the side.”
