Bowen has an ankle injury and Graham a knee problem, with club officials to make a call on their fitness when they receive scan results this morning. NSW forward Luke O'Donnell is also hopeful of returning from a hand injury against the Dragons.
Meanwhile, Queensland Origin fullback Karmichael Hunt will have surgery on his broken right foot in Brisbane today.
Hunt suffered the injury in Brisbane's 18-16 loss to St George Illawarra last Friday night. Hunt is expected to be out for eight weeks and return for the Broncos' round 24 clash against the Bulldogs at Sydney.
