SP Hunters coach, Michael Marum said Watson has been playing well off the bench which pushed him into the starting side.
“The combination with brother Ase and Gahuna will allow them to steer the team around the park,” said Marum.
In other changes made- Israel Eliab goes to the centres, Bland Abavu shifts back to fullback and Stargroth Amean will play on the wing. Karo Kauna Jr. will start on the other wing.
Marum said Radley Brawa will become Hunter #52 when he starts off the bench this weekend.
“Wellington Albert has been sidelined for two weeks by the QRL judiciary after he was cited for a shoulder charge.
“Moses Meninga was cleared of the lifting charge and will start in the second row alongside Nixon Put,” said Marum.
William Aquila, Wawa Paul and Butler Morris have been named on the extended bench.
The 20 man squad (two to be omitted): Bland Abavu, Stargroth Amean, Israel Eliab, Willie Minoga, Karo Kauna, Jnr, Ase Boas (Captain), Watson Boas, Henry Wan, Gahuna Silas, Esau Siune, Nixon Put, Moses Meninga, Stanton Albert, Noel Joel, Enock Maki, Ismael Balkawa, Radley Brawa, William Aquila, Wawa Paul and Butler Morris.
The final 18 man team departs for Cairns on Thursday, then onwards to Mackay.
