Parramatta superstar Jarryd Hayne is in danger of missing State of Origin II after being put on report for headbutting in the Eels' 24-10 win over Melbourne in Friday night's spiteful grand final rematch. In an absorbing first meeting between the two sides since the decider that never was - with Melbourne stripped of their 2009 premiership for repeated salary cap breaches - emotions which had been kept mostly in check for most of the night exploded midway through the second half. Hayne found himself in hot water after tangling with opposite Billy Slater, referee Tony Archer leaving the NSW Origin winger in little doubt as to how costly his 62nd minute blow to the head of his Australian teammate could become. "There's a lot to lose with the weeks leading up," Archer told Hayne during his caution, no doubt alluding to upcoming Origin matches. "You've got a lot to lose with the weeks ahead." Hayne could find himself joined on the Origin sidelines by Slater as well, the Storm fullback sin-binned after retaliating with what appeared to be a elbow to the head of Hayne four minutes later. The incident wasn't put on report but will surely come under the watchful eye of the match review committee, Slater binned along with Eels halfback Daniel Mortimer after the incident sparked a brawl.
