ADELAIDE youngster Tyson Stengle has been suspended for four AFL matches and fined $2500 by the club after being caught drink-driving in an unregistered vehicle earlier this month.

Stengle's fine will be donated to charity, while he will also be forced to undertake a road safety education program after he was pulled over by South Australian police and returned a blood alcohol reading of 0.125 on April 9.

CROWS' SHUTDOWN REPORT CARD Weapons, downfall, more

The club-imposed sanction was determined by senior management who took into account the 21-year-old's delayed reporting of the indiscretion.

The suspension is due to have added significance, given the season has already been reduced to just 17 matches per team in the wake of the game's shutdown due to the global COVID-19 outbreak.

"I know that I have let a lot of people down and I want to apologise for what were some poor decisions," Stengle said in a statement on Tuesday.

"I am determined to win back the trust of my teammates and coaches and that starts with focusing on my training and working hard."

Stengle has played just three senior matches for Adelaide, but was identified as a key member of its developing team and featured in the club's round one loss to Sydney.

The club announced the news of his indiscretion on Friday evening, just hours after it was revealed Western Bulldogs midfielder Lachie Hunter had been involved in a drink-driving incident where it was alleged he crashed into four parked cars.
