Hooker Mitch Rein hurts shoulder as Dragons injury toll mounts Dragons hooker Mitch Rein leaves the field with a shoulder injury. DRAGONS hooker Mitch Rein will undergo scans next week after leaving the field with a painful shoulder injury in last night's Charity Shield loss to South Sydney. A repeat of their 2012 attacking woes shaped as St George Illawarra's biggest headache until halftime, when International three-quarters Jason Nightingale (glute) and Matt Cooper (calf) failed to return. But the biggest scare arrived when Rein - selected as part of the NSW Origin Emerging Blues squad - was left writhing in agony 15 minutes from fulltime. The Kiama junior walked straight to the sideline clutching his left shoulder and Dragons coach Steve Price confirmed the injury would be monitored. Further misfortune then struck a minute later when Rein's understudy, Cameron King, was knocked senseless while attempting to burrow through Rabbitohs giant George Burgess. While adamant that Cooper and Nightingale would be available for the team's first-round clash against premiers Melbourne on 9 March, Price could not guarantee Rein's health until he has scans. "He's got a bit of a burner there on his shoulder, so we'll let it settle down over the weekend and he'll get scans early in the week," Price said. Our medical staff don't seem to be too concerned by it. With new halves combination Jamie Soward and Nathan Fein still a work in progress, Rein and King emerged St George Illawarra's creative playmakers last night. Rein stepped up with a delightfully timed pass to send Trent Merrin across the stripe, shortly after Daniel Vidot squirmed over to open their account in the 56th minute. "I was pleased with the way the guys fought back from 16-0 to get back to 16-10," Price said.
