The NRL has concluded its Integrity Unit investigation into Josh Addo-Carr, with his camp told on Tuesday that the case was closed, according to News Corp.
The decision followed a negative B-sample result in early November, clearing Addo-Carr of a second positive drug test.
He had tested positive during a random roadside drug test in September and entered a rehabilitation facility on the Central Coast after learning the result.
The veteran had also tested positive within the previous two years, leading the Canterbury Bulldogs to release him after the 2024 season.
Before the B-sample result, the Eels considered releasing the winger, but allowed him to return after a meeting.
Reports said a positive second test could have brought a 12-game suspension and put his playing future at risk, despite his community work.
Addo-Carr's lawyer, Elias Tabchouri, said he was grateful for the process.
"We're very happy that has come to an end," Addo-Carr's lawyer Elias Tabchouri told the publication.
"I can't credit the Parramatta Eels or the NRL more for the way this matter was addressed.
