Cronulla star Josh Dugan's stuttering NRL campaign has hit another hurdle after being ruled out for up a month with a lower leg injury.

Dugan was two weeks into a return from a broken foot that forced him to miss a fortnight, while he was also sidelined for another two matches earlier this season.

Sione Katoa has been drafted into Friday's NRL clash against South Sydney and will play on the wing, with Edrick Lee moving to fullback.
