ROOSTERS forward Boyd Cordner has been ruled out of football for 4-6 weeks in a major blow to the NSW State of Origin hopes in the return game at Suncorp Stadium.

Cordner, who was voted the Blues best player by his teammates, had scans on a foot injury this morning which revealed he needs at least a month off.

His injury at least opens the door for Blues coach Laure Daley to bring boom Panthers forward Bryce Cartwright into the side, although St George Illawarra back rower Tyson Frizell would be the favourite.

The Roosters have yet to announce a replacement for their game against the Tigers at Allianz Stadium on Sunday.
