SYDNEY ROOSTERS players claim fans threw full beer bottles at them last night as the drama on the field continued off it following the Warriors' 30-13 win at Mt Smart Stadium.

Roosters chief executive Brian Canavan described as disgraceful the actions of fans, who threw bottles at his players into the in-goal area during the second half, and urged the NRL and the Warriors to find the culprits.

The rowdy fans vented their fury on the visitors immediately after Lance Hohaia's 45th-minute try - which took the Warriors back to within a point of the lead - after the Roosters had been earlier awarded a first-half penalty try, which later led to calls from Warriors coach Ivan Cleary for the video referee to be scrapped.

"I saw them flying past me," Roosters five-eighth Braith Anasta said of the beer bottles. "It was a low act - too many beers. They shouldn't be allowed back."

Fullback Anthony Minichiello added: "One just missed me. They were full beer bottles. What's going on?"

Canavan believes the bottles were plastic, however, some Roosters players claimed they were glass. After the incident, referee Tony Archer went to the sideline in an effort to make the ground manager aware of the allegations by the Roosters.

Canavan said: "It's a safety issue for all teams. It's very disappointing when fans supporting any team resort to that sort of disgraceful behaviour.

"Mark O'Meley just mentioned it to me. He said he noticed it.

"They're the entertainers. They're the ones they come to watch. It's something all stadiums have to be very stringent on.

"I'm quite sure the NRL will be very diligent in finding these people."

NRL chief operating officer Graham Annesley said he would act on the incident. "We'll talk to the stadium about it," he said.

The 31st-minute penalty try also dominated discussions after the match. It was awarded by video referee Steve Clark, who believed Hohaia had taken out Minichiello as the two jostled for the ball.

"I've been saying all year, I'm not a fan of the video ref, and tonight … personally, I just think it's an absolute lottery," Cleary said.

"There were two blokes going for the ball, in a do-or-die game - how it was a deliberate foul, I can't see. I'm just really glad it didn't affect the outcome of the game. I just think when it goes to the video, I think everybody has no idea what's going to happen. That's not what it's for. It's there to make sure everything's right.

"It just holds the game up, and a lot of time … it's [not] clear-cut, and everyone's left shaking their heads afterwards."

Warriors prop Ruben Wiki, whose NRL career has been prolonged by the gripping victory, paid tribute to his teammates for not allowing the decision to affect them. "Calls like that can change the game," he said. "The response of our players when they looked at the big screen was awesome."

Roosters coach Brad Fittler's box was next to Clark's, and he asked the official about the decision at half-time, something that is discouraged by the league.

Minichiello was sure he would have scored, saying: "I know I got pushed. I could have dived on it with my chest."

The Roosters fullback has been the subject of intense speculation about his future, and last night's match was possibly his last for the club.

He is believed to have been targeted by European rugby, and while he did not exactly rule out the prospect of a code switch, he did say: "I'm under contract. I haven't negotiated with anyone. I'd never say never, but I haven't negotiated with anyone."

Fittler was as tight-lipped. "I've got no idea," the coach said.

As they had against the Broncos a week earlier, the Roosters capitulated in the second half last night after leading 13-6 at the break.

"We'll have to take half-time out of the game," Fittler said. "We lacked that hardness. We got a bit soft a few crucial times. That's something we're going to have to work on." Next year.
