Dugan Origin injury could be serious

NSW centre Josh Dugan could be set for another stint on the sidelines after suffering a jaw injury in the Blues' 18-14 win in State of Origin III.

St George Illawarra star Dugan, who missed games one and two with an elbow injury, left the ANZ Stadium clash on Wednesday night midway through the second half.

"It could be serious," Blues coach Laurie Daley said when asked about the injury in his post-match press conference.
