A Manhattan businessman who once was a backup quarterback at Kansas State has been ordered to spend two years and eight months in prison for improper sexual contact with a former high school student.

38-year-old Zach Burton was sentenced Tuesday in Riley County after telling the judge that his actions were “selfish,” and that he never coached or had the female student in class.

Authorities have said the female student went to Riley County High School, where Burton was an assistant boys’ basketball coach and substitute teacher.

Burton pleaded guilty in September to one count of unlawful sexual relations. He owns a business called Fieldhouse Development Inc.
