Roosters prop Sam Moa has warned the NRL that diving has become a blight on rugby league after Friday night's fiery encounter between the premiers and Bulldogs.

The Warriors are being fuelled by an unconventional - and somewhat controversial - nutrition programme.

The Warriors will aim to hit much higher heights, but this was a step in the right direction.

Sydney Roosters coach Trent Robinson and captain Anthony Minichiello accused Canterbury players of diving for penalties in a sensational aftermath to the NRL premiers' 32-12 win at ANZ Stadium on Friday night.

The Warriors set a goal pre-season to be the best defensive team in the NRL. It seemed a laughable ambition in the early weeks as they leaked the most points of any side in the competition, but a change has occurred.

Newcastle star Willie Mason says the Knights' players have resolved to give their all regardless of the crisis gripping the NRL club's front office.

He is not the backline marquee signing that fans may have hoped for but the Warriors believe Matt Allwood can add valuable depth to the troublesome centre area.

The Warriors were unable to celebrate Andrew McFadden's permanent appointment with a win, being tipped over by the table-topping Bulldogs in Hamilton today.

The Sydney Roosters' NRL pain could turn into more woe for NSW after the visitors suffered a 42-10 mauling by North Queensland and had Blues hopeful Boyd Cordner hobble off with an ankle injury.

Wests Tigers winger David Nofoaluma has been accused by Cronulla's Wade Graham of biting as the visitors secured a come-from-behind 22-20 NRL win over the Sharks at Remondis Stadium on Saturday night.

Thomas Leuluai could return to action in the next month - but another scenario may see him not play again this season.

The NRL are guilty of failing to reinforce the rules they introduced to clamp down on the lifting tackle, writes Hugh McGahan.

Dean Bell is in a good mood. Not only does he believe the Warriors are on the verge of "something special" but he's just had his own contract extended until the end of 2016.

Kevin Locke says his relationship with Sam Tomkins is "awesome", despite the different trajectories their respective careers have taken.

The only man under as much pressure to help deliver NSW a drought-breaking State of Origin series victory as coach Laurie Daley and embattled playmaker Mitchell Pearce is chief selector Bob Fulton.

St George Illawarra Dragons fans are the most unforgiving in the NRL.

Andrew McFadden's first official act as Warriors' head coach was to plump for stability, naming an unchanged team yesterday for Sunday's match against the top of the table Bulldogs.

The Warriors have a chequered history with rookie NRL coaches but see little risk in appointing Andrew McFadden to a long-term deal.

The next four weeks could define the Warriors' season.
