Graham out for 4-6 weeks

North Queensland utility Ash Graham has been ruled out for four to six weeks with a knee injury suffered in the Cowboys' weekend loss to Parramatta.

It was first feared that Graham had suffered a season-ending knee injury but scans today revealed grade two medial ligament damage.

Young forward Scott Bolton injured his ribs against the Eels but is expected to line up against the Bulldogs at Suncorp Stadium on Friday night. North Queensland will also be sweating on the fitness of Origin stars Carl Webb - who is already battling a hamstring twinge - as well as Johnathan Thurston and Jacob Lillyman.
