Josh Addo-Carr's time at Canterbury appears over as he prepares to front the Bulldogs board in the wake of his drug-driving scandal.

AAP understands the Bulldogs have issued the former State of Origin winger a show cause notice, with his future set to be determined when he appears before club powerbrokers next week.

Addo-Carr has looked at long odds to see out the final year of his contract since further analysis of a roadside drug test taken in early September confirmed a positive reading for cocaine.

The saga cast a shadow over the Bulldogs' return to the finals for the first time since 2016, with Addo-Carr opting to miss the elimination-final loss to Manly rather than spark a media circus.

Addo-Carr also caught backlash for misleading Bulldogs officials about the incident, and has previously run afoul of club higher-ups over a brawl at last year's Koori Knockout competition.

The winger was given a four-game ban by the NRL over his latest indiscretion, to go with a three-month suspension from driving and $682 fine issued by police.

Canterbury's decision to sign replacement winger Marcelo Montoya earlier this month appeared another blow to Addo-Carr's hopes of remaining with at the club.

St George Illawarra have been linked with the winger as they look to add speed to their ongoing rebuild.
