Canterbury are expected to assess their short-term plans concerning Josh Addo-Carr on Tuesday ahead of Sunday's elimination final with Manly amid allegations the winger returned a positive roadside drug test on Friday night.

On Tuesday, veteran rugby league reporter Danny Weidler reported Addo-Carr is expected to be stood-down for the Bulldogs first final since 2016 ahead of scheduled meetings at the club.

It comes after reports emerged on Monday alleging Addo-Carr, after being pulled over in Sydney's suburbs, came back positive for cocaine in initial tests before secondary tests were taken for analysis.

"About 10.45pm on Friday (6 September 2024), officers attached to Auburn Police Area Command were patrolling Baywater Drive, Wentworth Point, when they stopped a Toyota hatchback for random testing," a NSW Police statement used by a number of outlets on Monday reportedly read.

"The driver - a 29-year-old man - was subject to roadside testing which allegedly returned a positive indication for cocaine. The sample has been sent for analysis."

Speaking on Nine's 100% Footy Monday night, Bulldogs footy general manager Phil Gould said Addo-Carr "vehemently defends himself" against the allegations with apparent conflicting interpretations of the incident.

"He did, in fact, test positive at the scene. He felt it was inconclusive. The policeman did say it was positive," Gould said.

"Now, what Josh thought was because he went and did the second test, and they allowed him to go. He thought that was negative. That's where he was getting the thought, well, I've got no case to answer.

"I'm not saying that Josh was deliberately misrepresenting. That was his interpretation of the events. The police have a different interpretation. At the end of the day, the second drug test will tell the tale."

Gould said Addo-Carr made the Bulldogs aware he had been tested the previous night on Saturday morning, later adding the footballer "vehemently defends himself that he shouldn't be testing positive to anything, that he hasn't taken anything that he would test positive to".

It was repeatedly stated Addo-Carr was allowed to drive home from the scene.

The 29-year-old, with his management, had a face-to-face meeting with Gould on Monday afternoon "to go through exactly how things unfolded and what's happened", the Bulldogs footy boss said.

Gould added there had been no attempt over a "cover-up" from the club, and made no suggestion Addo-Carr had attempted to mislead officials in his recount of events.

He said the winger had offered to undertake separate blood and urine tests.

Earlier on Monday, Gould had taken to social media to deny any allegations of a positive result.

"On Friday evening Josh was pulled over and subjected to a random roadside drug test. The test results were negative and Josh was allowed to continue on his way. Happens to all of us at some stage on the roads. It's the Police keeping the community safe. We appreciate their work," Gould wrote.

"There is absolutely no truth to rumours that Josh had any issue. None whatsoever. Enjoy your finals football everyone."

Addo-Carr did not feature in Canterbury's 44-6 thumping from finals-bound North Queensland in Homebush on Saturday due to an ankle injury.

He was expected to be fit for a return in the first week of finals.

Asked if Addo-Carr would play in the club's return to the postseason for the first time since in close to a decade, Gould confirmed another sit-down would take place on Tuesday.

"Josh has had a lot going on in his life in recent times. Injury, family, people close to him with their families, and now this. It's been a tough time for him off the field, and we've got to be mindful of the fact that we've got a big game, and we can't be distracted," Gould said.

"Josh has indicated that he wants to play. I've spoken to the NRL integrity unit tonight, and as of this point, they would have no reason to stop him from playing, but that's really now a discussion for the coach and the chairman. When I sit down with them tomorrow and Josh again, and once we get a little bit more information."

Addo-Carr has scored 11 tries from 14 appearances across the 2024 season.

It's expected the secondary tests taken roadside will be returned in the coming days.

Between the early hours of Thursday and Monday morning NSW Police conducted 10,885 Random Drug Tests with 470 drivers returned a positive result within the broader traffic operation labelled RAID (operation), NSW Police said in a broader media release on Monday.

Addo-Carr did not attend a Bulldogs club presentation night on Monday.
