Fresno State has signed football coach Tim DeRuyter to a new contract that runs through the 2018 season, the school reported Friday on its athletic website. The deal has been in the works since January.

The contract reportedly is 100 percent guaranteed, meaning if DeRuyter is let go for any reason, Fresno has to pay DeRuyter all that is remaining in unpaid salary.

"We are elated and encouraged with the tremendous success that Bulldog football has achieved under Tim's leadership these past two years," athletic director Thomas Boeh said. "The execution of these agreements illustrate Fresno State's clear commitment to establishing stability within the program on behalf of our student-athletes and the Red Wave."

The 51-year-old DeRuyter has led the Bulldogs to a 20-5 record in two seasons and back-to-back consecutive Mountain West Conference championships, Fresno State's first consecutive conference titles since 1992 and 1993.

"It's very gratifying to know that our administration is pleased with the direction that the football program is headed and wants to show its commitment to our future," DeRuyter said.

"I would like to thank our President Dr. Joseph Castro, Director of Athletics Thomas Boeh, the Athletic Corporation and the administration for their support as our football staff and I continue to strive for championships and make the Valley proud of its team."

DeRuyter will have a base salary of $1.4 million this season, which will escalate to $1.6 million by 2018.
