The Australian selectors and head coach Tim Sheens today added five Toyota Cowboys to the train-on squad for the upcoming Four Nations Tournament and Prime Minister’s XIII match against Papua New Guinea.

Not surprisingly, current Test players Matthew Scott, Johnathan Thurston and James Tamou had their names included on the shortlist.

Fullback Michael Morgan has been rewarded for his outstanding 2014 season by gaining his call-up while Gavin Cooper is in line to retain the PM’s XIII jersey he earned for the first time last year.

A final squad for the annual match against the PNG Kumuls at Kokopo on Sunday 12 October will be announced next Monday.

The Four Nations squad for the series against New Zealand, Great Britain and Samoa will be selected after the PM’s match.

The NRL revealed today that a number of players had been forced to withdraw from the train-on squad due to injury, including Dale Copley, Justin Hodges, Matt Gillett, Brett Morris, Josh Dugan, Trent Merrin, Will Hopoate, Andrew Fifita, Michael Gordon, Billy Slater, Aidan Sezer and Dave Taylor.
