Both Matai and Asotasi switched allegiance from NZ to Samoa for the Cup and Asotasi captained Samoa in an international against Tonga in April. They would have been the two biggest names in a strong Samoa squad that also includes the likes of Reni Maitua, Antonio Winterstein, David Fa'alogo and Mose Masoe, citing a desire to represent their families as the main motivation.
Asotasi is said to be struggling with an arm injury and Matai is nursing a shoulder complaint but might be included in the touring party in an administration role.
Probable Samoa squad: Roy Asotasi (Rabbitohs), David Fa'alogo (Knights), Pita Godinet (Warriors), Harrison Hansen (Wigan), Masada Iosefa (Wests Tigers), Faleniu Iosi (Letava Bulldogs), Tim Lafai (Bulldogs), Joseph Leilua (Knights), Teofilo Lepou (Marist Saints), Reni Maitua (Eels), Penani Manumeasili (Sharks), Mose Masoe (Panthers), Suaia Matagi (Warriors), Arden McCarthy (Point Chevalier), Anthony Milford (Raiders), Junior Moors (Storm), Edward Purcell (Warriors), Ben Roberts (Eels), Iosia Soliola (St Helens), Sauaso Sue (Wests Tigers), Mark Taufua (Sharks), Ionatana Tino (Apia Barracudas), Daniel Vidot (Dragons), Antonio Winterstein (Broncos).
