NRL: Warriors stick with winning formula against Penrith Panthers

Warriors coach Stephen Kearney has named an unchanged squad for Friday's clash with the Penrith Panthers in Sydney.

Kearney has stuck with the formula that produced a gutsy 26-18 comeback win over the St George Illawarra Dragons in last weekend's NRL Magic Round in Brisbane.

There's some doubt regarding the availability of Nathaniel Roache (back), Tohu Harris (knee) and Jazz Tevaga (foot), who all sat out Tuesday's training.

Kearney expects the latter two to be ready to go come Friday, although there's slightly more concern surrounding Roache, who will be given until game day to prove his fitness.

"I don't have a crystal ball but we'll give him every chance," Kearney said. 

"He's gotten better every day. A couple of travel legs in between - a flight back (from Australia) and a flight back over so that all needs to be taken into account.

"You try to give him his best opportunity to play as possible."

Karl Lawton - who impressed against the Dragons off the bench - would step in to start at hooker if Roache is deemed unable to play.

Meanwhile, big name players Issac Luke and Adam Blair remain out of favour, named to  an extended bench alongside Gerard Beale and Chanel Harris-Tavita.

All four will run out for the reserves grade side on Saturday, unless Luke is called in to cover for Roache.

The Western Sydney-based Panthers have struggled in recent weeks and are currently mired in a five-game losing streak.

Kearney believes it's a scenario that only adds danger to the task at his side's hands, as they look to string together consecutive wins for the first time this season.

"It's the challenge for us, we're walking into a bit of a hornets nest this week.

"We have an expectation of what we're going to be confronted with but our focus is on what we need to do. I've had enough to worry about here, than worry about some other footy club and their woes."
