Sean O'Sullivan has been named to make his Warriors debut in this weekend's NRL match against the Raiders in Canberra.

The young ex-Broncos and Roosters half will partner Kodi Nikorima in place of Chanel Harris-Tavita.

The 21-year-old is out for 12 weeks after sustaining a stress fracture in his left foot, which he picked up in Friday's 20-16 loss to the Newcastle Knights.

Coach Nathan Brown says it's an unfortunate setback, but he's a good visual learner who can pick things up quickly.

Prop Bunty Afoa has been name to start in place of Jamayne Taunoa-Brown who is suspended for his side's next three games.

Ex-Raider Jack Murchie moves onto the bench.
