Mark Helfrich has signed a $17.5 million contract extension with Oregon through 2019.

"Mark has provided tremendous leadership of our football program and the values and character that he insists upon are in line with our mission as an institution," Oregon athletic director Rob Mullens said in a statement. "The success of our student-athletes on the field and in the classroom will continue with Mark's leadership and we are thrilled that he will stay at home in Oregon for a long time to come."

Helfrich led Oregon to the College Football Playoff National Championship in his second with the Ducks.
