Manu Samoa will step up their preparations for Rugby World Cup 2019 in Japan with games against Tonga, the USA and Fiji from 27 July.
Jackson has rewarded prop Alofaaga Sao, flanker Tofatuimoana Solia and winger Johnny Vaili for their impressive form in Samoa’s domestic Super 9 competition with a place in the group.
Second-row Senio Toleafoa, number eight Afa Amosa, UJ Seuteni, former New Zealand and Samoa sevens star Belgium Tuatagaloa (pictured) and Western Force flanker Henry Stowers have also been included for the first time.
It means that there are more new faces in the squad than players with previous Rugby World Cup experience. Only five players who appeared at England 2015 - Motu Matu’u, Teofilo Paulo, Jack Lam, Faifili Levave and Rey Lee-lo - have made the cut, while Logovi’i Mulipola represented Samoa in New Zealand four years earlier.
“I've watched it over the last couple of weeks, the semis and the final and previously a couple of round robin fixtures as well and the quality of rugby over here in that Super 9 competition is quite outstanding,” Jackson said.
“I think it's probably one of the better finals I've seen for a long long time, in terms of club, that I witnessed on the weekend and out of the semi-finals we picked up a prop in Alofaaga Sao - he's only 21 and he's got a bright future in the game.
“We can always look at New Zealand and Australia and other clubs around the world but I think we've got the same sort of quality players here and it's just about us now as a coach and a management group giving them the tools so they can be as good as they possibly can be, not only in the PNC but the Rugby World Cup and beyond."
Samoa have qualified for every Rugby World Cup since the second edition, in 1991, but have failed to navigate the pool stage since the turn of the century.
Four years ago Samoa opened their Pool B campaign with a 25-16 win over the USA but subsequent defeats to South Africa, Japan and Scotland - by just three points - consigned them to an early exit.
Jackson’s side will again come up against Scotland and hosts Japan in Pool A of this year’s tournament, and will also meet Ireland and Russia as they bid to reach the quarter-finals proper for the first time since 1995.
In preparation for their trip to Japan, Manu Samoa will face Tonga in Apia on 27 July in the first round of the Pacific Nations Cup before travelling to Suva for games against the USA and Fiji on 3 and 10 August.
