HULL centre Kirk Yeaman will make his Great Britain debut in Saturday's Gillette Tri-Nations clash against Australia in Sydney.
The 23-year-old, pictured below, comes into the starting line-up in place of Martin Gleeson.
That's the only change to the backs that started against New Zealand last Saturday and was beaten 18-14.
It means Giants winger Martin Aspinwall must again wait for his full Great Britain debut as he also misses out on a place on the bench.
But St Helens forward Jon Wilkin will make his Test bow as a substitute in place of Gareth Carvell.
Gareth Hock starts in the second row with Adrian Morley on the bench but coach Brian Noble admitted that he might yet reshuffle the squad.
Carvell is dropped from the 17-man squad, while former Giants centre Gleeson has been axed after concerns over his partnership with winger Brian Carney in GB's opening defeat by New Zealand.
Inclusion in the side at Aussie Stadium caps a roller-coaster season for Yeaman, who missed three months of the domestic campaign with an ankle ligament injury but still finished as one of engage Super League's top tryscorers with an impressive tally of 23.
"They've been on fire all season with their respective clubs," Noble said of the debutants.
"They've been great in practice, very enthusiastic and their attitude has been terrific.
"Jon Wilkin especially was unlucky to miss out last week, so he's now going to get the opportunity."
Opponents Australia have made five changes to the line-up that claimed a thrilling 20-15 comeback victory over the Kiwis in game two.
But Noble has dismissed any claims that the changes have weakened the in-form Kangaroos, who have already booked a place in the final with two wins over the Kiwis.
"You'd have to say there's still some pretty handy players in there," he added.
"They've got some strike off the bench and they're starting big and strong as well with Willie Mason in the back row and Jamie Lyon in the centre.
"It's a talented team, but they can do two or three of those teams and still be very strong.
"That's our challenge, but we're excited."
