Warriors coach Nathan Brown could hand 18-year-old Reece Walsh a debut against the Melbourne Storm this weekend

Walsh has been named on an extended bench for Sunday's NRL game, leaving the door open to a debut if Brown decides to tinker with the 17 he's named.

Teams have to name squads of 21 on Tuesday and cut them as game time draws closer.

Injuries have meant a new centre combination, with Peta Hiku and Adam Pompey suffering injuries against the Dragons along with emergency replacement Paul Turner.

That means Marcelo Montoya moves back from the wing, with David Fusitu'a fit again from a hamstring injury while second-rower Jack Murchie will fill the other centre berth this week.

Second rower Bayley Sironen is back from injury on the interchange after missing the last two games with a shoulder issue.
