Penrith fullback Dylan Edwards is in line for a maiden representative jersey after being called into Australia's extended squad for the Pacific Test series.

Edwards's absence was one of the only controversies from coach Mal Meninga's squad named ahead of the first match against Samoa on October 14.

But the triple premiership winner has been added as a late addition as cover for Josh Addo-Carr, who has been hit with a breach notice by the NRL for an incident at the Koori Knockout competition.

"It is alleged Addo-Carr engaged in conduct which has brought the game into disrepute by punching an opposition player to the head following a match," the NRL statement read.

The breach notice does not specify any punishment for Addo-Carr, but flags that he has five business days to respond.

Known for his reliability in defence and out of yardage, Edwards has been one of the Panthers' most important and improved players during their four NRL seasons of dominance.

He received the Clive Churchill Medal for his man-of-the-match performance in their 2022 grand final victory over Parramatta and polled the eighth most votes in this year's Dally M Medal count.

But captain James Tedesco has had a mortgage on the NSW and Australian fullback spots since before Penrith's resurgence, leaving Edwards the only three-time premiership Panther yet to play representative footy.

The 27-year-old made his NRL debut as an outside back and had been suggested by pundits as an option at wing for NSW's State of Origin side this year, though was ultimately overlooked.

With a dearth of specialist wingers in Meninga's squad, Edwards could find himself called onto the edge for a Kangaroos debut.
