Coach Nathan Brown has finalised his side to take on the Panthers in Round 4, with a number of changes and an NRL debutant.

Pete Mata'utia shifts to fullback, with younger brother Sione Mata'utia taking his place in the centres alongside Nathan Ross.

Luke Yates moves into the second row for Sione Mata'utia, while 2017 recruit Joe Wardle (Player #284) is set to make his NRL debut from the bench.

Having played the first three rounds of the season in reserve grade on his comeback from off-season knee surgery, Wardle will provide utility value at either centre or second row.

Josh King and Jacob Gagan drop off the extended bench.

The match kicks off at 6pm.
