The NRL integrity unit has been made aware of a video being shopped to media outlets allegedly showing a Brisbane player using cocaine.
The Seven Network reported on Saturday that it had been offered a video, purporting to show a Broncos player sniffing a substance off a pub toilet seat.
The player, who cannot be clearly identified, has denied the claim.
The integrity unit has asked the club to look into it but the game's administrators have not launched a formal investigation.
The person who filmed the video has offered it to several media outlets for between $50,000 and $70,000.
