NSW Origin hopes go pop as Eels star Jarryd Hayne injures hamstring in loss to Roosters PARRAMATTA superstar Jarryd Hayne is in severe doubt for State of Origin II after suffering a hamstring injury in last night's 38-24 loss to the Roosters. On a night when the Eels put up a brave fight after a week of turmoil, the injury to Hayne was a huge blow for Parramatta - and potentially NSW. Hayne told a Parramatta trainer: "I heard a pop." The full extent of Hayne's injury will be known today after he has an MRI scan. If Hayne is ruled out it could open the door for Josh Dugan to make a shock return for the Blues - while Brett Stewart would be an option, although he hasn't played for several weeks because of a back injury. Parramatta coach Ricky Stuart was last night hoping Hayne could make it back in time for the second Origin game in Brisbane on June 26. "We will do everything we can for him to give him the best chance for Origin," Stuart said. Stuart said the early indication was that it might be only a grade one tear but there were also reports last night that the star fullback could be sidelined for between four and six weeks. Eels star Jarryd Hayne is helped off the field after injuring his hamstring against the Roosters at Parramatta Stadium. Hayne collapsed to the turf in the 74th minute clutching his right hamstring, and immediately told the Parramatta trainer: "I heard a pop."

Our physio Vicki will definitely know exactly what it will take once they know the grading of the hammy. But Parramatta's physio, Vicki Locke, would not speculate last night on the potential damage or how long Hayne could be sidelined. Hayne was chasing a Chris Sandow chip kick late in the game when the injury occurred after he fell awkwardly. He came off the field almost immediately afterwards. Hayne was inspirational for NSW on Wednesday night and his loss would be a crushing blow after such a great win for the Blues. Parramatta coach Ricky Stuart prepares to send Jarryd Hayne on against the Roosters. He scored the opening try with a piece of individual brilliance and his defence was outstanding. If he is ruled out it would open the door for Dugan to possibly come into the team. When Dugan was sacked by Canberra earlier this year for drinking on a rooftop with Blues rookie Blake Ferguson, Laurie Daley refused to rule him out of playing any part in the series. Dugan was man-of-the-match in his first game back for St George Illawarra and has been steady since. The Dragons take on the Knights in Newcastle today and by the time Dugan runs out the extent of Hayne's injury should be known.
