The immediate future of Cronulla star Ben Barba is unclear amid reports he tested positive to cocaine after his team's grand final win.
Barba was tested four days after the Sharks beat Melbourne Storm in October, News Corp Australia reported on Tuesday.
If confirmed, Barba could face a 12-match NRL suspension under the code's drugs policy.
The NRL has refused to comment at this time.
Triple M is seeking comment from the Cronulla Sharks.
