Cronulla Sharks five-eighth Braydon Trindall has been stood down effective immediately after failing a roadside alcohol and drug test.

The Sharks have released a statement confirming the five-eighth is now waiting for further testing results after an alleged positive cocaine reading per The Sydney Morning Herald.

"Sharks NRL squad member Braydon Trindall failed initial roadside alcohol and illicit drug tests early on Monday morning," the club wrote.

"The Club has since followed the appropriate protocols within the player's contract and CBA and continues to work with the NRL integrity unit, with the Club, player and his management agreeing it is in Braydon's best interest to not participate in games or to train for the short term, most importantly to attend to his welfare and health issues.

"Trindall reported the result of the roadside tests immediately to Sharks management, who in turn informed the NRL integrity unit.

"The matter has been referred for a court appearance in May where Trindall will face the allegations and charges levelled against him, noting that a secondary sample of the illicit drug test is yet to be confirmed.

"The Sharks treat these issues extremely seriously, however they are providing Trindall with the necessary welfare support.

"Until more information is available the Club will make no further comment."

His standing down means the Sharks will miss Trindall for at least this weekend's clash with the Canberra Raiders away from home.

The Sydney Morning Herald are reporting that the Sharks's five-eighth was already suspended from driving for previous offences when he was tested on Monday morning after Cronulla's win over the North Queensland Cowboys.

There it's alleged cocaine was found in his system on the roadside test, although Trindall is now waiting for results from an oral fluid test which will provide a more accurate result.

The Sharks will make no further comment, while the NRL are yet to comment with the integrity unit investigating.

Trindall has played 57 NRL games.
