The Crows say they're again investigating Stengle, who was caught drink-driving and then in possession of drugs in separate incidents this year.

"Stengle ... has been stood down from all club duties effective immediately as the club ascertains all relevant details on the situation," the Crows said in a statement on Monday.

"The club is working closely with the AFL and AFL Players Association as well as Stengle's management in relation to this matter."

Stengle was twice suspended for four games for separate off-field indiscretions this year.

In April, the Crows banned Stengle for four AFL games after he was caught drink-driving.

At the 22-year-old's court hearing in October, Stengle also admitted driving while his licence was suspended and driving an unregistered car when pulled over by police.

Stengle blew 0.125 in a blood alcohol test. He was fined $1600.

His court appearance in late October came a month after he and then-teammate Brad Crouch were suspended by the AFL after being caught with illicit drugs.

Stengle was again banned four games and Crouch was suspended for two games when the AFL found the pair guilty of "conduct unbecoming" after an investigation in to the September incident.

The pair were caught by police with an illicit substance, believed to be cocaine, in Adelaide's central business district at 5.15am on September 28.

Stengle and Crouch, who was traded to St Kilda at the end of the season, were given a so-called first strike against them under the AFL's drugs policy.

They were ordered to attend a drug and alcohol education course prior to next season but police didn't charge the duo, instead referring them to counselling under a drug diversion program.

The latest Stengle incident comes a day after the Crows revealed another player, Josh Worrell, had been caught drink-driving.

Worrell, the No.28 pick from the 2019 national draft, was stopped by police in Adelaide's western suburbs at about 9am Sunday after staying overnight at a teammate's house.

The 19-year-old, who holds a probationary driver's licence, was found to have a low-level prescribed concentration of alcohol in his blood (0.056).

Under South Australian laws, it's illegal for probationary drivers to have any alcohol in their system.

Worrell was also issued with an expiation notice for using his mobile phone while driving.

Adelaide's head of football Adam Kelly said on Sunday, while it was a police matter, the Crows were considering their own sanctions on Worrell, who has yet to play an AFL game.
