WESTS Tigers prop Todd Payten believes the Willie Mason hit that knocked him out in Saturday night's Foundation Cup at the Sydney Football Stadium was not intentional and should not result in a judiciary charge for the star Roosters recruit.

The NRL video review committee will study footage of the 58th-minute incident, but after watching replays of the tackle by Mason and Roosters teammates Nate Myles and Anthony Tupou, Payten said he was the victim of an accident.

"I've seen it a few times today and I don't think there was anything intentional in it," Payten said. "Willie's about a foot taller than everyone else and I think he's just rushed in with his shoulder and bounced off them. I don't remember much but I think he hit me in the side of the head - in the temple - and my lights went out."

Payten said he was still feeling "groggy" yesterday but was hopeful of being cleared to play in next Saturday night's trial against the Titans.

"I've been knocked out before but never for that long," he said. "A few of the boys phoned me today to see how I was, so they must have been worried. But if the doc says I'm OK, I want to play. I want to get some game time under my belt before round one if I can."

Fellow Tigers prop Ryan O'Hara, who was also injured in the 34-28 loss, will today have a plate inserted in his jaw after suffering two fractures in an area near where he had a wisdom tooth removed a few weeks earlier. He is expected to be out for eight weeks.

The Roosters also suffered a serious injury, with prop Shane Shackleton tearing his biceps tendon from the bone. He will be out for four months but skipper Craig Fitzgibbon (concussion) and utility Riley Brown (corked thigh) are expected to be fit for next weekend's hitout against the Eels.

Meanwhile, Broncos pair Justin Hodges (knee) and Peter Wallace (hip flexor) will be rested from further trials after suffering injuries in their 32-16 loss to Canberra.

Gold Coast second-rower Anthony Laffranchi received some good news yesterday when he was cleared of a serious knee injury after putting his leg through a floorboard as he stepped out of a spa at a Cairns hotel following Saturday night's 30-22 win over North Queensland.

In other news, St George Illawarra captain Mark Gasnier threw his support behind the dual refereeing system being trialled by the NRL after two referees controlled Saturday night's clash against the Bulldogs in Wollongong.

"You don't notice the guy at the back, which is a good thing," Gasnier said. "It's not like he got in the way too much, there was no confusion there between the two and then you've still got the video referee to go to. I couldn't take too many negatives out of it. It'll probably just cost the NRL a bit more in wages."

Elsewhere, Penrith are set to block any attempt by Craig Gower to return to the NRL this season - a move his agent, Greg Willett, yesterday insisted was unlikely.

Gower, who gained a release from the Panthers at the end of last season to play rugby union in France, has been linked to the Bulldogs, but officials from both clubs and Willet said they were not aware of any plan for him to come home early.

If Gower wanted to resume playing league within the next two years, he would need permission from Penrith to play elsewhere - a request the club would be unlikely to give.
