1:32 PM PT — Savarino has posted bail and is out of jail, according to online records.

The grandson of legendary Duke basketball coach Mike Krzyzewski was arrested for DWI over the weekend … after cops say he was driving over the legal limit when he struck and killed a 15-year-old boy on a bike.

The tragic accident occurred around 9 PM in Durham, NC on Saturday … when officials stated the boy rode in front of Joseph Savarino‘s Ford Explorer as they traveled in the same direction.

Cops say Savarino’s vehicle collided with the boy … who died at the scene.

According to court documents obtained by TMZ Sports, Savarino admitted to drinking earlier in the night … and registered a .11 on a breathalyzer, above the .08 legal limit, at 12:45 AM.

Savarino was booked in jail … and on Monday, his bail was set at $100K.

He surrendered his license for at least 30 days as a result of the incident. He is due in court in a month.

Savarino’s brother, Michael, was a walk-on at Duke prior to Coach K’s retirement. In 2021, Michael was arrested for DWI … an incident where now-Orlando Magic star Paolo Banchero was also charged with aiding and abetting DWI.
