Brisbane Broncos pay price in shock loss to the Parramatta Eels An instinctive field goal on the stroke of half time by Jarryd Hayne has proved the difference between Parramatta Brisbane, with the Eels clinging on to a one pont victory at Parramatta Stadium. BEN Hannant is in doubt for the Origin opener after he and Brisbane cohort Scott Prince suffered injuries during last night's boilover loss. In a night of spite at Parramatta Stadium, the embattled Eels outplayed the Broncos, bolting to a 10-0 lead after six minutes before holding their nerve to repel Brisbane in a thrilling final quarter. The loss was salt to the wound for the Broncos, who fought desperately after losing Prince to a hamstring injury in the 13th minute and Hannant to a calf problem seven minutes from time. Compounding their plight, prop Josh McGuire could have a case to answer after being reported in the 29th minute for a high-shot on Eels fullback Jarryd Hayne. It was that type of night for the Broncos, who trailed 11-8 at half-time and 17-8 after 44 minutes before tries to Justin Hodges (59th) and Ben Hunt (68th) provided a scintilla of hope. But the Eels survived a pulsating final 12 minutes to consign Brisbane to a 4-5 win-loss record ahead of the Broncos' derby clash with the Titans this Friday night. Hannant and Prince will have scans today but neither are expected to face the Titans and the former will be racing the clock for Origin I on June 5 after leaving the sheds on crutches. Broncos coach Anthony Griffin said injuries were no excuse as he blasted his side's lack of enthusiasm from the opening seconds. "We just killed ourselves," he lamented. It was one of those games where we were never on top. We didn't have the attitude to get ourselves on top until it was too late. We've got some injuries, but we had a team out there tonight who should have still been strong enough. There is no excuse for that. We just weren't good enough. We gave them 10 points start and no disrespect to Parramatta, they have been playing really well, but it's disappointing to come up with that type of performance. We have no right to expect we will get anything if we're not prepared to knuckle down and grind a game out. We are just hoping at the moment. The match was willing and it exploded in the 48th minute when a late shot from Eels forward Mitchell Allgood on halfback Peter Wallace sparked a wild brawl. McGuire raced in to throw a punch at Allgood and chaos broke out as about 15 players charged into the fracas. When the dust settled, Allgood was sin-binned first, then McGuire followed as irate Eels fans called for his dismissal. McGuire said later he was confident he would be cleared by the match-review committee, but Broncos skipper Sam Thaiday rued his side's insipid opening. "The biggest thing letting us down at the moment is our starts," he said. We lack enthusiasm, we lack mongrel, we lacked the killer instinct to win a game, that's where we are falling down at the moment. We are showing grit and determination late in the halves to try and come back but it's too late by then. We should be in there from the first minute _ not the last minute. Ahead 11-8 at half-time, the Eels turned up the heat on the Broncos after the break and it took just four minutes for Chris Sandow to put Joseph Paulo over for a 17-8 lead. Outplayed for most of the night, the Broncos refused to wilt, but the Eels were never going to lose a battle of wills. "It got into a bit of a war out there," Eels coach Ricky Stuart said. We have had a really healthy attitude the last two weeks. We had to show a fair bit of attitude, that's why we won the game.
