The football coach at Lakeville South High School has resigned amid an unspecified investigation.
Administrators say a complaint was filed against Tyler Krebs, who was placed on leave from his business education teaching post.
His resignation as football coach took effect Monday, but Krebs was not on the sidelines for last Friday's Lakeville South win over Eastview.
In an email to parents, school officials said because of the Minnesota Data Practices Act, information about the probe cannot be released.
Taking over the Cougars program is offensive coordinator Ben Burk.
Krebs has been head coach at Lakeville South since 2017. He was head coach at Burnsville for six years, and an assistant at Eastview for 14 seasons.
