Former NFL coach Jack Del Rio, who has served as a senior adviser to Wisconsin football head coach Luke Fickell this season, was arrested after allegedly driving under the influence and crashing into a street sign and fence, per ESPN's Adam Rittenberg.
Madison police said Del Rio "showed signs of impairment."
"We take matters like this very seriously and we are continuing to gather information," Wisconsin said in a statement via Rittenberg.
Fickell announced on Monday that Del Rio resigned following his arrest:
Before joining Wisconsin this season, Del Rio spent over two decades in the NFL with the New Orleans Saints as a strength and conditioning coach (1997-98); the Baltimore Ravens as a linebackers coach (1999-01); the Carolina Panthers as a defensive coordinator (2002); the Jacksonville Jaguars as a head coach (2003-11); the Denver Broncos as a defensive coordinator (2012-14); the then-Oakland Raiders as a head coach (2015-17); and the then-Washington Football Team as a defensive coordinator (2020-23).
