Coach K Calls Grandson's Arrest 'Violation Of Our Standards,' 'We're Handling It'

Mike Krzyzewski is clearly upset over his grandson's weekend arrest ... 'cause the Duke coach told reporters Tuesday he considers it a "violation of our standards."

The 74-year-old -- who's in his final season as the Blue Devils' head man -- spoke for the first time publicly about Michael Savarino's Sunday arrest ... and he promised he and his team will "handle that."

Unclear what any sort of punishment will be -- but it should be noted, Savarino, who's been playing for Coach K since 2019, was not spotted at Duke's game Tuesday against Gardner-Webb.

"We're already handling it," the coach said after beating Gardner-Webb, 92-52. "But, it's a violation of our standards. That's it."

As we previously reported, Savarino was arrested after cops say he showed signs of impairment during a routine traffic stop Sunday at around 1:10 a.m.

Authorities say the 20-year-old blew a .08 while in custody ... and was ultimately hit with three charges, including DWI.

His passenger, Duke star Paolo Banchero, was also hit with an aiding and abetting charge over the incident ... but unlike Savarino, Coach K allowed Banchero to start Tuesday.

The freshman forward played 26 minutes in the win, scoring 10 points.

"It's two different situations," Coach K said of why he started Banchero but sidelined Savarino. "Two entirely different situations. Headlines might make it look like it's the same -- it's not."

Krzyzewski added, "The decisions we made are in conjunction with our authorities -- our superiors. We're taking action. We took action and we will continue to take action."
