According to Bruce Feldman of Fox Sports, the deal is a five-year extension worth $16.25 million.
"I appreciate the confidence in me the Board of Regents demonstrated by approving this extension," MacIntyre said in a statement. "I look forward to continuing to contribute to the success of our student-athletes in the classroom and community and on the football field."
The school was investigating how the 2016 Associated Press Coach of the Year handled an allegation of domestic violence by the girlfriend of former assistant coach Joe Tumpkin. MacIntyre allowed Tumpkin to call defensive plays in the Buffaloes' bowl game in December because there was no official police or legal complaint against the staff member.
As a result of the investigation, MacIntyre will donate $100,000 to domestic violence organizations.
