Kiwis selectors have picked entire 19 man squad from the NRL for this Friday's Anzac test in Brisbane
Inu has only played one first grade game but has been included as the squad's only specialist fullback with Brent Webb unavailable as his partner has just given birth.
Former Kiwis halfback Gary Freeman says there is not a clear cut choice for the fullback jersey and he is backing Wests Tigers centre Paul Whatuira to fill the position for Friday's test.
Freeman believes Roberts is the right man for the job as he can step up to the job very well following the extra responsibility he has been given by the Bulldogs this year.
No players from the UK Superleague have been selected, while Warriors utility Lance Hohaia has missed out after picking up a head injury in his side's win over North Queensland.
The new captain to replace Ruben Wiki and the final 17 will be announced tomorrow afternoon.
The full squad is:
Roy Asotasi, Nathan Cayless, Greg Eastwood, David Fa'alogo, David Faiumu, Dene Halatau, Krisnan Inu, Simon Mannering, Benji Marshall, Frank Pritchard, Tony Puletua, Sam Rapira, Ben Roberts, Iosia Soliola, Evarn Tuimavave, Manu Vatuvei, Jake Webster, Paul Whatuira and Sonny Bill Williams.
